Presumably (I haven't looked at the sources of the package you're trying
to build) the configure.{ac,in} simply used
  AC_CHECK_LIB([pthread], [pthread_create])

which fails if pthread_create is a #define, which it is under the HP-UX
I'm looking at.

You can override the AC_CHECK_LIB test with something like
  ./configure ac_cv_lib_pthread_pthread_create=yes

The tests from the ACX_PTHREAD macro are smart enough to cope with this
situation.
