Comment (by barracuda156):

 Replying to [comment:3 ryandesign]:
 > The fix you proposed is obviously unacceptable for inclusion in MacPorts
 due to the gcc / PowerPC / Mac OS X 10.6 specifics you've used. If you
 want to help us fix this problem for everyone, please submit fixes that
 will work on all OS versions and processors.

 I recon it is required only on 10.6.8 when using Rosetta (on 10.5.8 PPC
 and 10.6 PPC it builds fine as-is).

 Like I asked in other ticket, can this be added conditionally?

 if {${os.major} == 10 && ${configure.build_arch} eq "ppc"} {
 configure.args-append       CC_FOR_BUILD="gcc-4.2 -arch ppc" \
                             CFLAGS_FOR_BUILD="-arch ppc" \
                             --build=powerpc-apple-darwin10 \
                             --with-ld=/usr/bin/ld \
                             --with-as=/usr/bin/as
 }

 (Probably `ld` and `as` are redundant, I can test what is the minimal
 addition that helps, if solution gets accepted in principle.)
