Any ruby extensions that use libpthread and are not linked with
-lpthread (which has issues and won't be added) need to
LD_PRELOAD=/usr/lib/libpthread.so.x.y.

Alternatively, you could try ruby 1.9 (sudo pkg_add -i
ruby19-rmagick), which links with libpthread and shouldn't have this
issue.

Just LD_PRELOAD=libpthread.so is enough, ld.so can pick the version
by itself.
