Oh cool.. I did not see the commit :(. I've eliminated the extra details,
and here's the new patch that gives details about what libraries *have* to
be linked into httpd. I'm not sure if this level of detail should be
documented at all or can I assume that the users should know what modules to
link.

shell implementation (/bin/sh) on FreeBSD. Be sure to use v2.13

+================
+ HP-UX:
+ The dlopen() system call in HP-UX has problems when loading/unloading
+ C++ modules. The problem can be resolved by using shl_load() instead
+ of dlopen(). This is fixed in the Apache 2.0.44 release.
+ To enable loading of C++ modules, the httpd binary has to be linked with
+ the following libraries :
+
+ HP-UX (11.0 / 11i):
+ When using shl_load : "cpprt0_stub.s -lcl"
+ When using dlopen : "cpprt0_stub.s -lcl -lCsup"
+
+ HP-UX (11i version 1.5 and greater):
+ When using dlopen/shl_load : "cpprt0_stub.s -lcl -lunwind"
+
+ The cpprt0_stub.s can be downloaded from the web site :
+
http://h21007.www2.hp.com/hpux-devtools/CXX/hpux-devtools.0107/0083.html
+ Compile cpprt0_stub.s with the PIC option
+ cc -c +z cpprt0_stub.s
+ - OR -
+ gcc -c -fPIC cpprt0_stub.s

Platform preference for shl_load on HPUX11 must be expressed by testing
first for that method. dlopen on HPUX11/64 bit OS'es or including one
off libdld's should not be recognized.
