print/enscript-a4 port test failure

[chukharev at mail.ru]

The 'port test' command (ports-mgmt/porttools) tests a port for a number of possible errors
by running portlint, building, packaging, installing, and de-installing with a check for
left files. This is done with defined PREFIX and PKG_DBDIR variables. 'port test' command
is recommended by the Porter's Handbook.

Note that the port installs the usual way.

When running 'port test' command in print/enscript-a4, the following output is generated
indicating fatal errors from portlint.
