Hi! All,

Thank for trying to help. No offense taken. I am a biologist and my Perl knowledge is limited to the book "Learning Perl", and have minimal Unix knowledge, which you can already tell from my question.

I am using MacOS 10.6.3 Terminal with Perl Version v5.10.0.

Terminal Shell is "tcsh".

Since I cannot find where Bundle::CPAN is located I cannot send you file permissions for it.

Thanks for your time. I really appreciate it.

What are the permissions on the files instmodsh and perldoc?

Have you tried $ perl -S instmodsh or $ perl -S perldoc?

When you get perldoc working try

$ perldoc -l strict
C:\perl\5.10.1\lib\strict.pm

$ perldoc -l HTML::Template
C:\perl\site\5.10.1\lib\HTML\Template.pm

$ perldoc -l Bundle::CPAN
No documentation found for "Bundle::CPAN".

$ which instmodsh
C:/perl/5.10.1/bin/instmodsh

$ perldoc -l instmodsh
C:\perl\5.10.1\bin\instmodsh

Alternatively

$ perl -Mstrict -le " print for values %INC"
C:/perl/5.10.1/lib/strict.pm

Thank you everyone. Someone from apple.com>Unix forum solved my problem. I needed to change the file permissions as below.

old file permissions:
-rw-rw-rw-  34 root    wheel         807 Jun 24  2009 instmodsh
-rw-rw-rw-  34 root    wheel         807 Jun 24  2009 perldoc
[download]

I set the execute bit using:

sudo chmod +x /usr/bin/instmodsh /usr/bin/perldoc

new file permissions:
-rwxrwxrwx  34 root    wheel         807 Jun 24  2009 perldoc
-rwxrwxrwx  34 root    wheel         807 Jun 24  2009 instmodsh
[download]

Now, it works!
