We’ve all been there -someone gives you some prewritten code to run and the first thing you try to do fails
[loggedin@host ~]$ ./prepared_script.pl -i infile -o outfile
Can’t locate Package/1.pm in @INC (@INC contains: /usr/local/lib64/perl5 /usr/local/share/perl5 at ./prepared_script.pl line 17.
So whats the problem? Well, essentially it is that the perl module (in this case it would be Package::1) isn’t available from your installation
The solution. You need to install the perl module (Package::1) into a local library and point perl at it. Here’s how…
1. find your package and download to your server
2. untar and navigate into the directory
tar -zxvf Package_1.tar.gz
3. build makefile specifying your local lib location
perl Makefile.PL PREFIX=~/lib/perl5 LIB=~/lib/perl5
make test #this will highlight other missing dependencies…
4. point perl to this library – easiest way is to add the following line to your login via ~/.bashrc in your favourite editor
export PERL5LIB=~/lib/perl5/ # save then source the file (source ~/.bashrc)
5. go back and do it all over again until it all works wonderfully
6. discover that the script you were given doesn’t do what you want anyway….
