Re: Perl install problems OSX 10.4.11

Hi, Thanks to all who have responded.

I have tried Packy Anderson suggestion but I found that some modules  
stated
that they only come as part of Perl 5.10.1. If I try to install them,  
it seem that
they want to be installed in a location other than that which I have  
specified.

I have Perl 5.10.1 installed but I don't know how set my environment  
so get_iplayer to use it.
MacPorts has set my environment to export PATH=/opt/local/bin:/opt/ 
local/sbin:$PATH
so the version of Perl (5.8.8) installed by MacPorts is being used by  
get_iplayer.

Is it possible to add the Perl 5.10.1 path to the environment so i  
don't loose the MacPort option.

I have reinstall Apple's developer tools from my system install disk.

Thanks,

Terrence
