Turned out to be a glibc problem.  I installed the latest glibc update 
from
RedHat (should have done that before), and now with

./configure --with-roken=/usr/heimdal --with-krb5=/usr/heimdal 
--without-krb4 --enable-smp CFLAGS="-DCONFIG_SMP=1 
-DOPENSSL_DES_LIBDES_COMPATIBILITY -DHAVE_OPENSSL"

arla compiles and runs.

I'm having a strange problem though where sometimes reads from afs will 
hang indefinitely.
Attaching to the hung process with strace will get things moving again. 
I guess thats because
strace interrupts and restarts the system call, and the restarted call 
goes through ok.

I also have lots of log messages like

  arla[879]: kernel: all 16 workers busy

Does this matter?

How would I get the latest cvs? I tried the instructions on the web 
site, and get...

$ cvs -d anoncvs at anoncvs.stacken.kth.se:/stacken-cvs checkout arla
cvs server: cannot find module `arla' - ignored
cvs [checkout aborted]: cannot expand modules

Thanks.
