[Mono-osx] 1.1.8.3 build failure on 10.4

[Benjamin Reed]

I'm attempting to update the Fink packages of mono to 1.1.8.3, and I'm
getting the following error during install:

---(snip!)---
make install-local
MONO_PATH="../../class/lib/net_1_1_bootstrap:$MONO_PATH"
/sw/source.build/mono-1.1.8.3-21/mono-1.1.8.3/runtime/mono-wrapper 
../../class/lib/net_1_1_bootstrap/gacutil.exe /i
../../class/lib/default/System.dll /f  /root
/sw/source.build/root-mono-1.1.8.3-21/sw/lib /package 1.0

** ERROR **: EnterCriticalSection: EnterCriticalSection failed: Invalid argument
aborting...
---(snip!)---

any ideas what's going on?
