That's right. Perl keeps around the various compiler and library
options that are necessary for building Perl extensions. If "-lgdbm"
is included in there then Perl itself was compiled with "-lgdbm" and
I would expect that
ldd /usr/bin/perl
would have a line showing a dependency on something like libgdbm.so.2.
I suppose it's possible that the Debian crowd messed up their Perl
build and linked statically against libgdbm.a when *they* built Perl
but that you don't have libgdbm.a installed on your system.
With Red Hat Linux, for example, the archive library libgdbm.a is in
the gdbm-devel RPM whereas the libgdbm.so stuff is all that most
people need and lives in the gdbm RPM.
