Comment (by bugmail-macports@…):

 Thanks for your answer.
 Indeed I have a couple of readline.h around, but not in /usr/local:

 {{{
 locate readline.h
 /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.8.sdk/usr/include/editline/readline.h
 /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.8.sdk/usr/include/readline/readline.h
 /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk/usr/include/editline/readline.h
 /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk/usr/include/readline/readline.h
 /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator7.1.sdk/usr/include/editline/readline.h
 /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator7.1.sdk/usr/include/readline/readline.h
 /opt/local/include/editline/readline.h
 /opt/local/include/readline/readline.h
 /opt/local/share/doc/readline/html/readline.html
 /opt/local/var/macports/sources/rsync.macports.org/release/tarballs/base/src/pextlib1.0/readline.h
 /usr/include/editline/readline.h
 /usr/include/readline/readline.h
 }}}

 The ones in /usr/include/editline/ and /opt/local/include/*line/ all have
 the same signature (that of the Xcode for MacOSX10.9.sdk):

 {{{
 /*      $NetBSD: readline.h,v 1.33 2012/05/15 17:30:04 christos Exp $   */
 }}}

 {{{
 SHA1(/opt/local/include/editline/readline.h)=
 36d79499fa4b1cb5885596d8b6feae802283a0c3
 SHA1(/usr/include/readline/readline.h)=
 36d79499fa4b1cb5885596d8b6feae802283a0c3
 SHA1(/usr/include/editline/readline.h)=
 36d79499fa4b1cb5885596d8b6feae802283a0c3
 }}}
 while that in /opt/local/include/readline comes from the FSF:
 {{{
 #define RL_READLINE_VERSION     0x0603          /* Readline 6.3 */
 }}}
 {{{
 SHA1(/opt/local/include/readline/readline.h)=
 eb43dd1ba2d57d996666c22cb13d31d9fedd485c
 }}}

 It's a big mess, not surprising it doesn't work.

 I also have multiple libreadline:

 {{{
 locate libreadline
 /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.8.sdk/usr/lib/libreadline.dylib
 /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk/usr/lib/libreadline.dylib
 /Library/Frameworks/R.framework/Versions/2.15/Resources/lib/libreadline.5.2.dylib
 /Library/Frameworks/R.framework/Versions/2.15/Resources/lib/libreadline.dylib
 /Library/Frameworks/R.framework/Versions/3.0/Resources/lib/libreadline.5.2.dylib
 /Library/Frameworks/R.framework/Versions/3.0/Resources/lib/libreadline.dylib
 /Library/Frameworks/R.framework/Versions/3.1/Resources/lib/libreadline.5.2.dylib
 /Library/Frameworks/R.framework/Versions/3.1/Resources/lib/libreadline.dylib
 /opt/local/lib/libreadline.6.2.dylib
 /opt/local/lib/libreadline.6.3.dylib
 /opt/local/lib/libreadline.6.dylib
 /opt/local/lib/libreadline.a
 /opt/local/lib/libreadline.dylib
 /usr/lib/libreadline.dylib
 }}}

 The one in /usr/lib doesn't contain _rl_username_completion_function. I
 attach it in nm.txt.


 Ok, then I tried to move /opt/local/include/*line and /usr/include/*line
 away but I get a different error:

 {{{

 }}}
 Apparently it is missing some headers... which one should I have kept?
