Well, that was useful advice and has generated the weirdest data yet...

[julian@cable static-debug-client-build]$ gdb /usr/local/svnstatic/bin/svn

[...blah blah blah...]

(gdb) break main
Breakpoint 1 at 0x804dfb2: file
../repos/subversion/clients/cmdline/main.c, line 844.
(gdb) s

I'd figure my whole system is hosed except I just compiled apache2 and a
new php and they both worked just fine.

Nothing terribly strange:

[julian@cable static-debug-client-build]$ ldd /usr/local/svnstatic/bin/svn
         libdb-4.0.so => /usr/local/BerkeleyDB.4.0/lib/libdb-4.0.so
(0x4001f000)
         libgdbm.so.2 => /usr/lib/libgdbm.so.2 (0x400a5000)
         libm.so.6 => /lib/libm.so.6 (0x400ac000)
         libcrypt.so.1 => /lib/libcrypt.so.1 (0x400ce000)
         libnsl.so.1 => /lib/libnsl.so.1 (0x400fc000)
         libdl.so.2 => /lib/libdl.so.2 (0x40113000)
         libz.so.1 => /usr/lib/libz.so.1 (0x40117000)
         libpthread.so.0 => /lib/libpthread.so.0 (0x40125000)
         libc.so.6 => /lib/libc.so.6 (0x4013c000)
         /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000)

Obviously there used to be more when it wasn't built static but they
didn't seem wrong then either.

That's where I built apache2 from... that could have been the problem
except we've now eliminated that by moving my installed apache2 out of
the way so configure can't find apr-config and apu-config.

Thanks for your help.
