[Koha-devel] perl installation on centos

Hi, Im trying to run Koha's perl installer on centos when i run this command- perl Makefile.PL .. i get the following msg... [root@koha ~]# perl Makefile.PL Can't open perl script "Makefile.PL": No such file or directory [root@koha ~]# I believe the solution to this is running the above command on -chmod... but could anyone please help me with how to run the -chmod for perl installation???? -Ro
