Oh and it is currently creating a folder in the directory when i run the installation:
/username/localperl
Ok, that's fine, but where is the new Perl executable? Is it under /username/localperl/bin? If so, is that in your path?
If not, then what you want to do is find where the current executables are (that are actually being called). Just type "which perl". From there, you should probably delete them and create softlinks to the new executables. At least, that is what I would do.
