Problems with CGI and mod_perl

Hello everyone

I have started since today learning how to write cgi in Perl with this
doc : http://users.easystreet.com/ovid/cg...lesson_one.html

I am running ubuntu on my pc and I installed the package mod_perl made
by ubuntu a few days ago and I was able to run Perl scripts from the
Apache. I read this doc to do it :
http://perl.apache.org/docs/2.0/use...start_fast.html

But while keeping on reading docs about Perl programming, I discovered
that it is possible to install modules directly from the command line
'perl -MCPAN -e shell'.

After installing some modules I didn't find in Ubuntu packages, the path
to per changed from originally /usr/bin/perl to /usr/local/bin/perl .

As a consequence,on my server where the perl scripts, I changed the path
to the Perl interpreter from /usr/bin/perl to /usr/local/bin/perl.

I have also reinstalled the Ubuntu mod_perl package but no change.
Finally, each time I want to run a simple Perl script on my server, my
browser asks me to download it.

I don't know what to do.
Thanks you very much for your help.

I don't know why paths would change after installing modules
with CPAN but /usr/bin/perl is typically a symbolic link to
/usr/local/bin/perl.

ln -s /usr/local/bin/perl /usr/bin/perl

I would try just the opposite, since on my Ubuntu, the default location
of perl is /usr/bin/perl, and it is not a symbolic link. So you can try
fixing your problem with:
sudo ln -s /usr/bin/perl /usr/local/bin/perl

When you ran perl -MCPAN -e shell
the first time, it probably asked you lots of questions and you probably
answered with the default answers. If you go into your cpan directory,
usually your home_directory/.cpan, and look in .cpan/CPAN, you can edit
MyConfig.pm to try to fix a difficulty.

I think, however, that the CPAN module checks perl -V output to see
where to install the new modules. You might tell us what you see when
you type:
which perl
perl -V
to help solve your problem.
