Hi,

can someone update FFTW packages for OpenMP capable?
just adding --enable-openmp on configure, i think.

Peace,

That's because there were many (32 in total) otherwise "internal" 
symbols are used by the threaded libraries which were not being 
exported, resulting in linking errors for the latter.  I fixed this in 
3.3.4-1, which will be available soon.
