install and use local perl module

stateless · 01-15-2013, 03:49 PM

Hi. I installed an application to a SUSE Linux system on which I have no root privileges. (Installed everything to folders in my own local directories.) Everything compiled and install fine, but after running it I discovered that the version of the DBI::db Perl module already on the system is too old, and so the app crashes because the module is missing an important function.

I haven't done any Perl programming for years, and don't remember much of anything. Could someone explain the quick and painless method of getting the newest version installed locally, and changing the environment so that the local version is used instead of the system one? I know how to do this with C/C++ programs, and Haskell, but not Perl.

I don't have permission to install a module on the system! may help.

Thank you for the help. I decided to try the CPAN approach, thinking that would be easier. However, after I try to install with 'install DBI' in the CPAN shell, the build process eventually dies with:

Code:

Could somebody explain this failure? It appears that "pgcc" does not recognize these flags, so why is CPAN trying to build with pgcc instead of gcc? If that is the problem, how do I change the default compiler?

I'm clueless on this secondary issue, sorry. I didn't mean to throw a curve at you.
