shouldn't it use -pthread?  (NOT -lpthread).

does it work and crash at the end?  that's what I see with the ImageMagick
import modules.  I tried several time to figure out what the problem is,
but I haven't figured it out yet.  I think it has something to do with
running in a thread(?).  a test program based on import_im works as expected.

maybe it's just an IM > 6 problem on *BSD?

is anyone able to use import_im or import_imlist without it crashing?
if so, what version of ImageMagick?
