Hi,
bash-2.02# perl -V:usedl -V:dlsrc -e 'print "$^O\n"'
usedl='define';
dlsrc='dl_dlopen.xs';

I tried the above as you'll have suggested. This seems to indicate that my
Perl 5.6 install does support dynamic loading.
Now, coming back to my original problem. Any ideas why it's unable to load a
shared object on the fly ?
Regards,
Soumen

The config variable usedl sets dynamic loading for perl:
% perl -V:usedl
usedl='define';
The variable dlsrc mentions which xs implementation of Dynaloader was
used. Perhaps the most common one is based on the dlopen() C RTL call
that was a part of POSIX (I think):
% perl -V:dlsrc
dlsrc='dl_dlopen.xs';
Although other values are possible, such as on VMS:
$ perl "-V:dlsrc"
dlsrc='dl_vms.c';
A value of dl_none.xs indicates a static only perl, for example:
$ perl -V:usedl -V:dlsrc -e 'print "$^O\n"'
usedl='undef';
dlsrc='dl_none.xs';

Without resorting to -V command line shorthands you can access those
variables (in a Makefile.PL for example) via the Config module as in:
use Config;
my $usedl = $Config{'usedl'};
my $dlsrc = $Config{'dlsrc'};
