In my experience HPUX's dlopen is still rather buggy. Other projects 
have reported the same, e.g.
http://marc.theaimsgroup.com/?l=apache-httpd-dev&m=104396627316847&w=2

Still, a configure switch to explicitly choose dlopen instead of 
shl_load may not be a bad idea, for people who absolutely have to have 
it. It's probably safer than mixing shl_load and dlopen in the same process.
