This bit me with CentOS 4.2 as well.  The problem is actually a typo in 
the kernel spinlock.h file. See:

<http://bugs.digium.com/view.php?id=6425>

and

<https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=180568>

for more information.

Here's a quick fix.  In your zaptel Makefile, add the following (line 38 
for 1.2.4) - THIS SHOLD BE ALL ONE LINE:

CFLAGS+=$(shell if uname -r | grep -q 2.6.9-34.EL; then echo 
"-Drw_lock_t=\"rwlock_t\""; fi)

This way, if this is fixed in the next kernel release, you won't need to 
make another change to the Makefile.
