No problem. It's just that the hpux10.20 box is shot down tomorrow, so I
cannot test this platform any more.

Do you mean subsequent linked binaries should not contain the location
the dependent shared library was originally targetted for?
Well, I can agree here. Patch#2 with the +cdp mess would avoid that.

But another try: It should work to *link* the shared libraries *with*
the absolute internal name, so in-package executables get this as
fallback path without the +cdp mess, and to *relink* the shared
libraries *without* the absolute internal name, but using the +cdp
linker flag once to drop the $inst_prefix_dir.

Another question:
HP-UX does support SHLIB_PATH for 32bit hppa, and both LD_LIBRARY_PATH
and SHLIB_PATH for hppa64 and ia64 (32/64), which can be enabled easily.

Is it preferred to use the runpath from an environment variable?

Thanks!
