After 'bmake build'ing the package, I added a line to /usr/pkgsrc/ 
lang/perl5/work/perl-5.8.8/hints/linux.sh:

ldflags="-lm -lpthread"

At which point the package built.  I was able to install & package,  
as well.  I'd imagine there'd need to be a little more logic in the  
hints file to detect for the specific edge case I'm encountering  
here, but from my digging, it appears that, at least on x86_64 the  
math functions need to have a separate, explicit math library linked  
and the same with the pthread lib?  Not exactly sure, but the above  
fix appeared to work.

Hope this helps someone else!

Thanks,
