It seems there must be an easier way for you to handle this
situation, because, as
tye said, how can Perl find the libraries
at your non-standard locations once you've installed this
module?
But anyway, you can change the content of the 'test' sections
of the Makefile by creating a MY::test subroutine in your
Makefile.PL. That routine will be passed an object (I don't know
what type it is; from the docs it looks like it might be of type
'MM'). You first call the SUPER::test to get the standard 'test'
section, then you can use regexps to modify it.
For example:
package MY;
sub test {
my $self = shift;
my $test = $self->SUPER::test(@_);
$test =~ s!(-I\$\(PERL_LIB\))!$1 -I/home/deaconblues/code/lib
+-I/opt/cd/dv/na/bin!;
$test;
}
