Comment (by ballapete):

 The build went fine on Snow Leopard. Then port found that autogen
 @5.18.12_0 needs to be rev-upgraded. This fails with (from `config.log`):

 {{{
 configure:14135: checking for pkg-config
 configure:14153: found /opt/local/bin/pkg-config
 configure:14165: result: /opt/local/bin/pkg-config
 configure:14190: checking pkg-config is at least version 0.9.0
 configure:14193: result: yes
 configure:14221: checking for guile 2.0
 configure:14224: $PKG_CONFIG --exists --print-errors "guile-$v"
 Package guile-2.0 was not found in the pkg-config search path.
 Perhaps you should add the directory containing `guile-2.0.pc'
 to the PKG_CONFIG_PATH environment variable
 No package 'guile-2.0' found
 configure:14227: $? = 1
 configure:14221: checking for guile 1.8
 configure:14224: $PKG_CONFIG --exists --print-errors "guile-$v"
 Package guile-1.8 was not found in the pkg-config search path.
 Perhaps you should add the directory containing `guile-1.8.pc'
 to the PKG_CONFIG_PATH environment variable
 No package 'guile-1.8' found
 configure:14227: $? = 1
 configure:14235: error:
 No Guile development packages were found.
 }}}

 This is because port installed `/opt/local/lib/pkgconfig/guile-2.2.pc`.
 `/opt/local/lib/pkgconfig/guile-2.0.pc` is gone…

 New ticket for `autogen`?
