trouble explaining shared objects in Perl

jimw54321 has asked for the wisdom of the Perl Monks concerning the following question:

Hi. I need some advice. Have been explaining for several days to some coworkers that some Perl modules, like DBI and DBD::Oracle, have underlying shared objects. My understanding is that these files cannot be simply copied from Solaris 9 to Solaris 10. Am I missing something? There is the misconception that even though the script does not change "use DBI;" that there is no platform dependent code underneath. Even showing them the ".so" files is not working. Also, I have showed DBI as an example where there is Perl.c. Help! Maybe I am not explaining right. Maybe I am not remembering my C compilation. Maybe... I do not know. Thanks.

Maybe just copy the files across and demonstrate that they do not work. `perl -E'sub Monkey::do{say$_,for@_,do{($monkey=[caller(0)]->[3])=~s{::}{ }and$monkey}}"Monkey say"->Monkey::do'`	[reply]

Short demonstration, use as `patch -p0` SOso-0.01.patch.txt tar up blib and copy it, then test as `prove -vb blib/t` or `perl -Mblib blib/t`	[reply]
