If your assertion(s) are correct, that dlopen does search the
LD_LIBRARY_PATH, and shl_load does not, I agree with adding the
flag then (provided that it will always pick up a full path to binary
before it will ever use the search logic, explicit needs to override
any path list.)

Thanks for that pointer.

It's not. On 32bit / 11.any - it's important to continue to use the solid
shl in place of dlfcn, because the original dlfcn is not a solution, you won't
find compatibility from 11.x to 11.x box. It's a shame HP didn't have the
foresight to entirely and robustly implement dlfcn with the introduction of
11.00.00 :( OTOH with 11.any - it's important we pick up and use dlfcn for
64 bit compiled code. Simply put, it's a mess, and I'd be happy to champion
a patch which carefully deploys shl consistently on 11 or prior w/32bit,
and dlfcn on 11 or later w/64bit and 12 or later w/32 bit.
Patches attached for preferring shl_load only on 32-bit and
HPUX11/10/9 and for adding DYNAMIC_PATH to shl_load calls based on
discussion above.
Appeared to do the right thing on 32-bit 11.11PARISC and 64-bit IA64,
