Build module on one box and move to another box?

| Hi folks,
Having worked around my CPAN mirror problems by abandoning the FTP URL
and going with an HTTP connection instead (Thanks for the suggestion
David :), I'm now faced with the fact that the box I'm on does not have
a compiler installed. "They" want me to install various modules (DBI.pm
and others) without installing a compiler...
Can this be done? Can I compile a module on one box and somehow install
the code on another?
Might this be as simple as copying over the contents of the directories
in @INC?
Thanks for the feedback!

Yes, it can, in principle, be done.

Hardly ever. Alas. Although it's most likely to work with pure Perl
modules, and least likely to work with anything compiled.
If you really need to do this, the only practical way I know of is to
set up an identical box (the "staging" machine) that you can really
install and test on. When you have something working on the staging
machine, you can copy that to the production system that lacks a
compiler. If it doesn't work when it gets there, either you didn't get
it all there properly, or the two boxes aren't really all that
identical, so you get to try again until you get it right. Or until
you get a compiler on the box, as nature intended.
Good luck with it!

I have had to do this before and it is possible iff both machines are
using the same OS at the same version/patch level. It is easier if
you download and build the modules by hand (rather than try to use
CPAN). Just get the module to the point of "make install" and copy
the directory over. Just make sure you install any dependencies
first. Oh, another gotcha is that since some Perl modules rely on
extrenal libraries you need to make sure the two systems have all of
the same libraries installed.

>=20
Thanks Tom and Chas for the responses.
It sounds like this is do-able, but not w/o some pain. Their desire to
have this done quickly (surprise!) might determine whether or not I get
a compiler ;)
If I do successfully make the attempt, I'll post my results.
Thanks for the help!

Dear Richard,
you might want to try the Activestate distribution (www.activestate.com)
if there is one available for your platform. Activestate uses a package
manager (PPM) and ships with it modules in binary format.
Best regards
Kai
