In rule init-unix, python.jam defines system-specific libraries to link against. There are special cases for SOLARIS, OSF, ...etc, but not for HP-UX. As a result, HP-UX falls into default clause: extra-libs = pthread dl util I don't know which flavour of Unix has libutil library, but HP-UX does not. Because of this issue, python library tests py-run fail to link on HP-UX. Attached patch fixes this issue. I ran 1.34 regression tests and verified, that python tests that previously would fail to link now succeed. I also verified, that the patch does not cause any regression. Please, apply it to HEAD and RC_1_34_0 branch.
