To whom it may concern,

The article seems to be nice. I tried to work out the same. I configures PERL5LIB variable as

PERL5LIB="/home/galaxy/perl5/lib/perl/5.8.8:/home/galaxy/perl5/lib/perl5:/home/galaxy/perl5/lib/perl/5.8:/home/galaxy/perl5/lib/site_perl"
and I put MyConfig.pm file in the /home/galaxy/.cpan/CPAN/ directory. I made editing in LIB and associated things in the MyConfig.pm file And I tried to install some modules that time the perl is looking to install in the default system wide directories not to the assigned locations by the user galaxy. I allocated a place in my home directory thats is
/home/galaxy/perl5
The Error message is
*Warning: You do not have permissions to install into
/usr/local/lib/perl/5.8.8 at /usr/share/perl/5.8/ExtUtils/Install.pm line
114.
Cannot forceunlink
/usr/local/lib/perl/5.8.8/auto/Bio/Graphics/Browser/CAlign/CAlign.so:
Permission denied at /usr/share/perl/5.8/File/Find.pm line 886
make:   [pure_site_install] Error 13*
It will be great if you can suggest me a way to overcome this.

Why did you do that? I'm not sure where you got the idea, but I cannot think of a single situation where it would be useful. $PERL5LIB contains additional lib/module path data - notably, it's used for private module install directories. You've used the system paths instead, which require root permissions if you want to write to them - and as a result, you're getting "Permission denied" messages, which is exactly what I'd expect.

Please try re-reading my article:

http://linuxgazette.net/139/okopnik.html

If you follow the instructions in it carefully - which are very explicit about how PERL5LIB should be set - they should work just fine. I just used a private module install yesterday, for a project I'm working on for a client, and it worked just fine.
