CodeWarrior 10 and MQX 3.6.2:
I was getting a linker error that the symbol _lwevent_get_signalled was not found.
After some research I found that the file lwe_gets.c where _lwevent_get_signalled is defined was not in the list of files to compile for the PSP.
Solution:
Add lwe_gets.c to PSP Generic/lwevent and rebuild the PSP.
