[Chicago-talk] Installing another Perl on same box

Hi,

I need to install a non-threaded version of Perl in addition to the distro 
provided threaded version (Debian Sarge).

I've read the INSTALL that comes with my Perl source (5.8.4).  And it seems 
like I can make it so that the non-threaded can use all the pure Perl modules 
already installed.

So I did

sh Configure -Dprefix=/opt/perl -des
make && make test

I've been holding off the "install" to make sure I don't F'up my box

below are the things I think one would need to know about the current distro 
install. 

Questions:

1) does everything look like it will work fine?

2) after install with my new Perl be able to find the existing pure Perl 
modules, by default?  Or will I always need to alter my PERL5LIB or @INC to 
find the installed modules?

thanks
Jay
