>Description:
math/atlas will not build with multithreaded support enabled without changing
the flag used to link against POSIX threads from -lpthread to -pthread. This
issue shows up on SMP machines cause Atlas doesn't ask to build with multithreading
support on single-CPU machines. The problem will occur under both 4.x and 5.x.
>How-To-Repeat:
On an i386 SMP machine:
cd /usr/ports/math/atlas
make
answer yes when asked to enable multithreaded support.
Wait for build to error out with unknown linker flag -lpthread.
>Fix:
cd /usr/ports/math/atlas
make patch
Apply the following patch to math/atlas/work/ATLAS/config.c

Build should finish without errors, after which you can "make install".
