actually what I got when using CPAN for gzip was just the string - 'gzip'

# perl -MCPAN -e shell

cpan shell -- CPAN exploration and modules installation (v1.61)
ReadLine support available (try 'install Bundle::CPAN')

cpan> o conf gzip
    gzip
[download]

like so

I have 2 possible paths to gzip

/bin/gzip and
/usr/bin/gzip I'll try both and get back to you
