Comment(by stephen@…):

 OK (well, not really OK, but I managed to butkus gcc/apple-ld into
 building):
 {{{
 sudo port -f uninstall py26-numpy
 sudo port clean py26-numpy
 sudo port install py26-numpy
 cd `port work py26-numpy`/numpy-1.5.1
 sudo /opt/local/bin/gfortran-mp-4.4 -v -Z -t -Wall -arch ppc
 build/temp.macosx-10.4-ppc-2.6/numpy/linalg/lapack_litemodule.o

 -latlas -lgfortran -o
 build/lib.macosx-10.4-ppc-2.6/numpy/linalg/lapack_lite.so -undefined
 dynamic_lookup -bundle
 sudo port install py26-numpy
 }}}

 I don't know if this build actually *works*, I don't know how to test it
 offhand.  (It's a direct dependency of at least 3 ports I have installed,
 and is currently blocking upgrade of about 15 ports.  But I didn't ask for
 it personally.)

 I don't know if the uninstall is necessary; sometimes that helps so I
 tried it.  It didn't help, but of course then I'm stuck without an
 installed port until I figure out how to install.  I'm in no mood to do
 further testing right now....

 The gfortran invocation is a modification of the one recorded in main.log
 just before the error message.  The additions to the gfortran invocation
 are the {{{-v -t -Z}}} options near the beginning of the command line and
 the {{{-L/usr/lib}}} option which is the last of the {{{-L}}} options.
 Presumably the {{{-v -t}}} can be omitted.

 Aha - py25-numpy has the same problems.  Yep, "port -u upgrade ...; cd
 ...; gfortran ...; port -u upgrade" works without uninstalling, and the
 "-v -t" flags to gfortran are unnecessary.  Once again, this build is
 untested, I don't know if it actually works.

 FWIW it seems to me that this is probably Apple ld screwage, not a problem
 with MacPorts or gcc.  Maybe someday I'll try GCC 4.5 (cf #24925, 2d to
 last comment by vince), but I bet it doesn't help.

 Platform much like the OP:
 {{{
 iBook G4 (PPC)
 Mac OS X "Tiger" 10.4.11
 MacPorts from svn, fresh sync of dports
 port build probably 3-4 months old (port -v sez "1.9.1").
 }}}
