I'm not sure why either of these is an issue, especially the first. I'm
using libwww on HP-UX 11.0, and Perl 5.6.0, and I've had no problems. I have
a threaded Perl, because the BerkeleyDB and DB_file modules wouldn't work
without it.
I am, however, a firm believer in building Perl myself. I'll use a pre-built
gcc, because I've never figured out how to build a compiler without a
compiler, but I prefer to build my own Perl, because I worry about
incompatible libraries, whatever. I'd suggest building Perl from scratch to
see if the problem won't go away.
