The only problem is that linuxthreads doesn't exist on FreeBSD/amd64. 
You have to use one of the native thread libraries.

Your choices on 5.4 are not that great.  I'd suggest libthr on 6.0 as 
the closest match to linuxthreads, but I don't recall if it is 
available on 5.4.  I have a feeling it isn't.  I have a feeling your 
choices are libc_r or libpthread (kse).  libpthread should smoke libc_r 
for disk IO performance in general.  But modern libthr (on 6.0+) should 
give it a serious run for its money.
