Comment (by aronnax@…):

 Replying to [comment:1 adfernandes@…]:
 > Hello - I'm reasonably familiar with condor, and I guess that I'd want
 to ask if you're sure that the mac version '''requires''' the single-
 threaded version? (As in "it really needs it because of the wonky things
 that condor does to the thread and run states of a process", not (and I'm
 sorry if this sounds snotty) "it requires single-threaded because that's
 how the condor packagers assumed would be simplest".

 I didn't look deeply into this because I was afraid that the answer might
 turn out to be that the single-threaded boost libraries are needed for
 {{{condor_compile}}}ing. I can certainly add a patch to the port to force
 the multithreaded libraries, and see what happens.
