I am trying to compile a package from pkgsrc for the first time and have a
basic question. If I'm compiling a more recent version of a program that I
already have, do I need to uninstall the previous version before compiling
and installing the new version? For example, I installed Perl 5.6.1nb1 a
while back, but now need nb7. I originally installed nb1 from a precompiled
binary. Do I need to pkg_delete the nb1 package before installing the nb7
one?

Thanks...
