Re^2: how to install perl 5.10.1 on ubuntu9.10?

Do not add /opt/perl/bin to your (or root's) $PATH.

What is wrong with prepending own's Perl bin dir to $PATH (not root's, agreed)? I do it all the time, no problems so far.

Always use the fully-qualified shebang line at the beginning of scripts that you explicitly want to use /opt/perl/bin/perl:

OK, this shows the occasional use-case for custom Perl. However, if you want your scripts to be portable, do not hard-code paths. Instead, set $PATH and use something like

#!/usr/bin/env perl
[download]

which is much more portable.

What is wrong with prepending own's Perl bin dir to $PATH (not root's, agreed)? Gah. I really need to create an account here so I can edit my posts. You're right, thanks for the correction. I should've written "Do not add /opt/perl/bin to root's $PATH". As you point out, prepending it to your own (not-root) $PATH works great. The only reason I can think of that you might not want to add it to your own (not root) $PATH is that, when logged in as yourself, you'll get used to always automatically getting /opt/perl/bin/perl, and then when you log in as root, you'll run some code may forget that you're back to getting /usr/bin/perl. :)	[reply]

do not hard-code paths You should always hard-code paths as part of the install process, otherwise use `/your/favorite/perl yourperlprogram`	[reply] [d/l]
