python style states that there are no spaces around = when naming parameters, so
dll_basename = name -> dll_basename=name

also, slightly more pythonic would be to use the '%' operator after the string

[gab, 2012/05/10 00:12:55]

Done.
Actually according to:
http://docs.python.org/library/string.html#format-examples
.format() is the "new" way to go (unless you need to be compatible with python
<= 2.5).

An interesting post on StackOverflow as to why format() is better:
