To know how to fix the reg-exp, we need to know how your version
of dvips identifies itself.

Can you reply to this email, including the lines that  dvips
prints when it first starts up.
In a terminal, or DOS window, or whatever, please try:
  dvips --help    or  dvips -help   or  dvips -h
  dvips --version  or   dvips -version  or  dvips -v
or whatever else might reveal the startup message.
Try several, in case the responses are different.

Also, the error may not be with the actual version string,
as the regex below should detect any of:
    dvips 5.94a
    DVIPS 5.94A
    dvipsk 5.94a
    dvips(k) 5.94a
and many other similar patterns.

So to check what is happening, can you please add some print lines:

>

print "\nSTAT:$stat, MSG=$msg";

print "; VERSION=$version\n";

:-)   Yes, that'll work, until you upgrade.  :-)

Please try adding the 'print' lines above, and send me the result
when you run  config  again.
