I don't see anything wrong with the parentheses in the map expression.
Perhaps it might have something to do with the string you're passing into
regex.compile: regular expressions, too, use parentheses when they compile
a pattern.  Maybe that error message is coming from the regular expression
engine, and not Python.

As a debugging tool, can you do the following?

###
gKeys = []
for pattern in gPats:
    print "I'm going to compile", pattern[0], "now."
    gKeys.append(regex.compile(pattern[0]))
###

It's longer, but it might give us some idea of what's going on.  Also, you
may want to use the "re" module instead of the "regex" library --- regex
is a bit deprecated.

Good luck!
