[qvwm-e:00307] compiling under SCO OpenServer 5.0.6

Hi all.  I'm new to qvwm.   I've been using qvwm under RedHat (works great!)
and would like to use it under SCO OpenServer 5.0.6.   I've downloaded qvwm
1.1.12 source and compiled it.  It compiled without any errors.   When
running qvwm I get a memory core dump instantly, even if running outside of
X.  gdb reports error 11 segmentation fault.   What should I look for to
correct my problem?      II'm using gcc 2.95.2 from SCO SkunkWare 2000 CD.
X does work under scosession, KDE or fvwm95.  libXpm, libc, libsocket.a,
libX11 and libXext are all found.    Thanks in advance,

James
