Yes I have libpth(-dev) installed:

ii  libpth-dev            2.0.7-10              The GNU Portable Threads 
ii  libpth20              2.0.7-10              The GNU Portable Threads

Yes using gcc-4.3.1 as reported, perhaps the CMakeLists.txt warning should be 
raised to an error - and compiling with 4.3.1 not allowed at all?

However I am also seeing this behaviour with gcc-4.1:
