Perl library path on install to custom location

[spolson]

The readme installation instructions when installing to a custom location, it says to add this path to the @INC:

export PERL5LIB=/Path/to/where/to/install/lib/perl5/site_perl

However it appears that this path is incorrect AND that it will overwrite any existing PERL5LIB. Recommend changing to:

export PERL5LIB=/Path/to/where/to/install/lib:${PERL5LIB}

(Alternatively, since the location of the libs is known at make time, you might consider automatically incorporating this INCLUDE into the script(s) during the make build.)
