Description: 
pigs (spelt pigz) fails to multithread on Solaris 8.

Workaround: use /usr/lib/lwp.

Suggest changing RPATH to use /usr/lib/lwp
LD_OPTIONS=-R/usr/lib/lwp


It's possible a patch will fix also, please find it, check it's still
public and put in checkinstall if you think the patch is the solution.

LD_LIBRARY_PATH works but RUNPATH does not as the lib is pulled in from
libpthread.so which does not have this runpath set. Any ideas?
