wx library trouble

[Patrick Scheibe]

Hi,

I compiled successful the wxHaskell lib.
But when I want to start ghci -package wx following error occurs:

Loading package concurrent-1.0 ... linking ... done.
Loading package wxcore-0.9 ... linking ... ghc-6.4.20050320: 
/home/izbifs/scheibe/built/lib/wxcore2.o: unknown symbol `wxcWakeUpIdle'
*** Deleting temp files
Deleting:
ghc-6.4.20050320: unable to load package `wxcore-0.9'


I have a running wxHaskell home. Same configuration... wxGtk version, 
wxhaskell version, same config options except of the prefix.
In university it is installed local but I set the LD_LIBRARY_PATH.

How can I figure out what's wrong? Can find out where and why the function 
`wxcWakeUpIdle' is available home and where are the differences?

Has anybody a good hint where to start or what to check?

Any help is welcome
Cheers
Patrick
