Yep, I've filed a bug against this. g77 cannot link a shared lib on
ppc, and f2c isn't available. The reference blas library is needed
for the atlas lib checks. Probably the easiest is to port f2c to
powerpc, if you'd like to help. Then I can NMU a blas, with
maintainers permission, to use it instead of g77 on the powerpc
platform, as with m68k.

Thanks for the tip. The binutils are all that is needed. However, I
checked on voltaire, and the standard assembler there didn't seem to
understand the altivec assembly code put out by the altivec gcc,
whereas the altivec assembler did. Am I doing something wrong?
Take care,
