That sounds wrong, as the point of tests would be to make sure the stuff
you are going to install would work with what you thought will be used
from the system.

If "isn't available in the tests" is the problem, is it possible to make
it available?  We are passing down SHELL_PATH from primary Makefile to t/
and you should be able to do the same for Perl path...

About the Test::WWW:Mechanize::CGI thing, how widely available is it?  I
do not think it is packaged for Debian nor Ubuntu, for example.
