I'm not clear whether you want the search to succeed if pageText
contains either, or if pageText contains "CatInternational" but not
"#acl InternationalGroup".

Whichever you want, you could use 2 simple separate regular expressions
or 1 more complicated regular expression.

Search for either:

search = re.compile("^#acl InternationalGroup.*\n", re.M).search(pagetext)
if not search:
     search = re.compile("^CatInternational.*\n", re.M).search(pagetext)
if search:
     ret = search.group()

Search for one but not the other:

search = re.compile("^CatInternational.*\n", re.M).search(pagetext)
if search:
     search_2 = re.compile("^#acl InternationalGroup.*\n", 
re.M).search(pagetext)
     if not search_2:
         ret = search.group()
