Here you can find my Scientfic Computing with Math::GSL Podcast from PDX.pm.( Stream, Download) In the talk I compare PDL and Math::GSL, talk about the Google Summer of Code 2008, and show off some of the subsystems that are currently working. I field some questions from the audience about whether Math::GSL does symbolic computing or parrallelized/vectorized computing (it doesn't, at least yet) and how exactly I turn Perl subroutine references into C function pointers. If you look at the presentation slides here while you listen, it is almost like being there!

I've just sent another dev release off to CPAN, 0.13_03 to test the recent Build changes that were necessary to get AMD64 boxen to correctly compile. It turns out that they really need the "-fPIC" flag at compilation and link time or else stuff blows up:

usr/bin/ld: BLAS_wrap.o: relocation R_X86_64_32S against `a local symbol' can not be used when making a shared object; recompile with -fPIC BLAS_wrap.o: could not read symbols: Bad valuecollect2: ld returned 1 exit statuserror building blib/arch/auto/Math/GSL/BLAS/BLAS.so file from 'BLAS_wrap.o' at inc/GSLBuilder.pm line 99.
