[IronPython] Line numbers missing from tracebacks with fepy 1.0, Mono 1.1.17

[Anthony Baxter]

Tracebacks appear to be missing line numbers on this install of
Ironpython (it's the IPCE 1.0 version, running against Mono 1.1.17).
Before I dig into this too far, is this a known issue?


Traceback (most recent call last):
  File chimp, line unknown, in Initialize
  File chimp, line unknown, in main
  File display, line unknown, in set_mode
  File surface, line unknown, in __init__
  File surface, line unknown, in __init__
