Comment(by rmstonecipher@…):

 Replying to [comment:9 carsomyr@…]:
 > Trojan, I think the reason for the patch failure is because qt4-mac is a
 moving target.  In any case, I've uploaded an updated Port patch archive.
 I've also uploaded the qt4-mac-devel Port archive for those who don't want
 to apply patches.

 Roy,[[br]]
 I tried testing your archive of qt4-mac-devel but came up with some
 UsingTheRightCompiler errors.[[br]]
 The Portfile uses reinplace to replace "g++" and "gcc" with
 ${configure.cc}, but the files in which the substitution would occur have
 been deprecated.[[br]][[br]]
 The following change to the Portfile fixes the error but is not the best
 solution:
 {{{
 @@ -120,5 +120,9
      # Ensure that correct C/C++ compilers are used.
 -    reinplace "s| g++\$| ${configure.cxx}|" \
 -        ${worksrcpath}/mkspecs/common/g++.conf
 -    reinplace "s| gcc\$| ${configure.cc}|"  \
 -        ${worksrcpath}/mkspecs/common/g++.conf
 +      reinplace "s| g++\$| ${configure.cxx}|" \
 +          ${worksrcpath}/mkspecs/common/g++-base.conf
 +      reinplace "s| g++\$| ${configure.cxx}|" \
 +          ${worksrcpath}/mkspecs/common/g++-unix.conf
 +      reinplace "s| gcc\$| ${configure.cc}|"  \
 +          ${worksrcpath}/mkspecs/common/g++-base.conf
 +      reinplace "s| gcc\$| ${configure.cc}|"  \
 +          ${worksrcpath}/mkspecs/common/g++-unix.conf
 }}}
 I am unsure of whether g++-base.conf or g++-unix.conf is used for
 Mac.[[br]][[br]]
 It would be better to use a patch to substitute a placeholder (e.g.
 "%%CONFIGURE.CC%%") in files which call "g++" or "gcc".[[br]]
 This placeholder could then be reinplace'd post-patch with
 "${configure.cc}".[[br]]
 If something changes upstream and the patch cannot be applied the
 maintainer can determine if (1) the patch is no longer necessary or (2)
 the patch needs to be updated to point to different files and/or
 lines.[[br]][[br]]
 Cheers,[[br]]
