Hello,

I am currently running Perl on 11 different platforms. I need help determining the best practice for dynamically switching libraries when one runs a different version of Perl on different platforms.

My requirements are:


When I moved the code to aix, I sorted out a few library issues and went back to check my changes on solaris. Solaris blew up and stated: 
perl $FOO/foo.pl -bla bla bla 
IO object version 1.20 does not match bootstrap parameter 1.15 at /usr
+/local/lib
/perl5/5.6.1//sun4-solaris/DynaLoader.pm line 225.
Compilation failed in require at /.../perl/lib/Custom_mods/logfile.
pm line 49.
BEGIN failed--compilation aborted at /.../perl/lib/Custom_mods/logf
ile.pm line 49.
Compilation failed in require at /abc/123/foo.pl line 9
3.
BEGIN failed--compilation aborted at /abc/123/foo.pl li
ne 93.

I think the problem here is that logfile.pm is looking for the Perl 5.6.1 version of Handle.pm, which is 1.21. The aix system is running Perl 5.005_03 and I am pointing to the accompanying version of handle.pm that is 1.1505. Because of the dependencies the Perl 5.005_03 flavored system is barfing now that I am trying to run it in the 5.6.1 environment.
Here are the versions of the IO modules that I am running:
Here are the Perl 5.005_03 versions of the IO modules that I am running:
Module		Version
File.pm		1.06021
Handle.pm	1.1505
Pipe		1.0902
Seekable	1.06
Select		1.10
Socket		1.1603

I have both flavors of the IO modules. The question is, how do I dynamically switch between them? I need to get everything running under 5.005_03, but if I can just switch it for solaris and windows I am golden (at least for the short term). What is the best practice to do this w/ or w/o the use of a BEGIN statement?
My Perl env on solaris is as follows: 
PERL_HOME=/usr/local/bin
PERL=/usr/local/bin/perl
PERL5LIB=/usr/local/lib/perl5/5.6.1/:/foo/custom/perl/lib
and on aix: 
PERL=/bin/perl
PERL5LIB=/usr/opt/perl5/lib/5.00503:/foo/custom/perl/lib
PERL_HOME=/bin

Thanks in advance for your help :)

P.S. I have no idea why I am seeing this: 

/usr/local/lib/perl5/5.6.1//sun4-solaris/DynaLoader.pm

There appear to be no libraries on the solaris box I am using other than for Perl 5.6.1. There is a Perl executable of version 5.00404. This probably is not related, but I want to make sure.
