I have to use Sun C 5.7 and Sun Fortran 95 8.1, producing ELF64's with F77='f90 -xcode=pic32 -xarch=v9' (also tried f77, no difference) and CC='cc -mt -xcode=pic32 -xarch=v9' I compiled Python 2.5 (--enable-shared) then built blas and lapack following http://www.scipy.org/Installing_SciPy/BuildingGeneral. I passed -L and -R to ld for each library directory. I had to pass -G to ld as well for the Fortran linking steps to prevent error of missing "main" symbol in crt1.o. However, "from scipy import special" fails as below beause of the _cephes module which has a bunch of Fortran constants in it: {{ Python 2.5 (r25:51908, Nov 20 2006, 02:58:57) [C] on sunos5 Type "help", "copyright", "credits" or "license" for more information.

Is there a workaround?
