PL/Perl on HPUX

When I run './configure --with-perl' for 7.3.1 on an HPUX 11.0 system I
get the error about it not being able to build PL/Perl because libperl
is not a shared library, as mentioned in the installation docs.  In my
case, I installed perl 5.8 using the package from the HP Porting &
Archive Center.  The doc for 7.3.1 suggests that libperl IS a shared
library for most 'recent perl versions', so it seems like it should
work.  But it doesn't.  Is there a way around this?  I checked the mail
archives and it looks like there's been some discussion of this, but no
clear answers (to me anyway).
