I kept getting dependency issues and ultimately the installation of perlbrew just failed.
I've installed Perlbrew on multiple OS X and Linux varieties with minimal issues. What "dependency issues" and errors are you having when the install fails?
After installing perl brew if I "switch" to the new perl version, while downloading modules, will it automatically install it for new perl version?What if I dont "switch" and "use" a specific Perl Version? While installing CPAN Modules, will that be automatically taken care of?
Perlbrew is pretty straightforward. Modules get installed to whichever version of Perl is currently in use.
