How can you verify your perl is installed correctly?

blackfoot has asked for the wisdom of the Perl Monks concerning the following question:

I would like to verify that I have installed perl correctly on Mac os x 10.2. I am able to get the right response for perl -v, but is there a way to do a deeper check and look for the remnants of previous versions?

It depends. Did you accept the default target location of `/usr/local`, or did you modify it? When you enter "`which perl`", what is returned? If you did not override the default target location, then yes, there are remnants, particularly in `/Library`, but they are not harmful as there may be multiple perls in your, uh, oyster. You would then need to control it all with the shebang and your path. I have two versions of perl running just fine on 10.3. There are documents on Apple's site that detail how to superimpose a new perl over the supplied version. Even if you don't do this, I recommend you find and read them.	[reply] [d/l] [select]
