2nd perl install?

[Bill Marrs]

If I can't find the mod_perl rpm I need, it's looking like I might need to 
build it from source.  I believe this would mean also building Perl and 
Apache from source.

Now, I have a redhat-installed Perl already.  From past discussions, the 
best idea seemed to be to create a 2nd perl installation for 
Apache/mod_perl to use, perhaps located in /usr/local.

The thing I'm fuzzy on is how to tell my mod_perl programs to use this 
mod_perl.  Is it enough to have the LoadModule line point to my 
build-from-scratch mod_perl.so?

Also, if I want to use this 2nd perl for scripts, is it as simple as 
changing the top line to #!/usr/local/bin/perl.  Do I have to worry about 
library pathes or environment variables?

I assume I'll need to keep separate lib/perl5 trees as well and I'll need 
to install the various cpan modules I use twice.

Any tips would be appreciated.
