Version of PostGreSQL: 6.4.3

Version of pgsql_perl5: 1.8.1

Okay, sorry to bother you, but the postgresql installation went fine, and
the perl installation barfed. I thought perhaps it was an old copy or
something, and so downloaded the latest copies of each. Again, postgresql
installs fine.
perl Makefile.PL works fine
make works
make test returns this:

PERL_DL_NONLAZY=1 /usr/bin/perl -Iblib/arch -Iblib/lib -I/usr/lib/perl5/5.00502/i586-linux -I/usr/lib/perl5/5.00502 test.pl
Can't load 'blib/arch/auto/Pg/Pg.so' for module Pg: File not found at /usr/lib/perl5/5.00502/i586-linux/DynaLoader.pm line 168.

at test.pl line 12
BEGIN failed--compilation aborted at test.pl line 12.
test failed
make: *** [test_dynamic] Error 2

Although blib/arch/auto/Pg/Pg.so is clearly there.
I know this probably interests you not at all, so I won't be surprised if
I don't get an answer, but if you could help, I'd greatly appreciate it.
Thanks very much
