William, please try:

Stas,
Thanks for the link. Unfortunately the error is occurring during the make
process so I never get a blib/arch/auto/APR/APR.so being created. I
tried running nm on the libapr-0.so.9 in my httpd-2.0.54 source
directory.
nm /usr/local/src/httpd-2.0.54/srclib/apr/.libs/libapr-0.so.9 | grep
os_thread_current
However, running that command without _current returns the following:
00015f3c T apr_os_thread_get
00015f48 T apr_os_threadkey_get
While debugging last week, I seem to remember reading that
apr_os_thread_get is synonymous with apr_os_thread_current. I wonder why
the later would not be defined?
William, as you can see from the source src/modules/perl/modperl_util.h
#if defined(MP_TRACE) && defined(APR_HAS_THREADS)
#define MP_TRACEf_TID "/tid 0x%lx"
#define MP_TRACEv_TID (unsigned long)apr_os_thread_current()
The symbol is available if APR_HAS_THREADS is defined. So the apr header
containing this definition found by mod_perl says that APR_HAS_THREADS is
defined, whereas the library it tries to link against was compiled with
threads disabled. Meaning that you have more than one libapr on your
system and the wrong library gets linked.
