R14B compile failure on Ubuntu 9.04

[andrew mmc]

Hi there,

I'm still having problems identifying what is the problem with compilation
on Ubuntu Jaunty:

pthread/ethr_event.c:92: Fatal error in wait__(): Function not implemented
(38)
make[3]: *** [../ebin/hipe_rtl.beam] Aborted
make[3]: Leaving directory `/usr/src/otp_src_R14B/lib/hipe/rtl'
make[2]: *** [opt] Error 2
make[2]: Leaving directory `/usr/src/otp_src_R14B/lib/hipe'
make[1]: *** [opt] Error 2
make[1]: Leaving directory `/usr/src/otp_src_R14B/lib'
make: *** [secondary_bootstrap_build] Error 2

the function not implemented is ETHR_FATAL_ERROR__()

What could be causing this error, does anyone know how I may fix it?

Thankyou,

Andrew
