** SOME PERL MODULES ARE MISSING ******************************

If you know where perl can find the missing modules, set
the PERL5LIB environment variable accordingly. Otherwise
just proceed and the missing modules will be installed
automatically.

To force the system to download missing perl modules, you can
do a `touch PERL_MODULES` before running `$GMAKE`

** CONFIGURE DONE **********************************************

Settings:

  PERL5LIB = ${PERL5LIB:-"not set"}
  PERL = $PERL

The Makefiles use GNU make functionality.
Continue installation with

  $GMAKE install
