Pierre,
I tried your suggestions with no luck. Whe I specify LD_LIBRARY_PATH, it
still pulls libpthread.so.0 from the /lib/tls:
ldd /opt/Navisphere/bin/naviagent
linux-gate.so.1 => (0xffffe000)
libnsl.so.1 => /lib/libnsl.so.1 (0xf7fb7000)

libm.so.6 => /lib/tls/libm.so.6 (0x0049b000)

/lib/ld-linux.so.2 (0x0034f000)
LD_LIBRARY_PATH=/usr/lib/i386-redhat-linux3E/lib/ ldd
/opt/Navisphere/bin/naviagent
linux-gate.so.1 => (0xffffe000)
libnsl.so.1 => /lib/libnsl.so.1 (0xf7fb7000)
libdl.so.2 => /lib/libdl.so.2 (0x00495000)
libm.so.6 => /lib/tls/libm.so.6 (0x0049b000)
libpthread.so.0 => /lib/tls/libpthread.so.0 (0x004ca000)
libc.so.6 => /lib/tls/libc.so.6 (0x00368000)
/lib/ld-linux.so.2 (0x0034f000)
Using LD_PRELOAD produced errors:

When that didn't work, I took a look at all the libpthread files on my
system:
for file in $(locate libpthread); do file $file; done

Nothing looks out of place or unusual. I took your advice and read the
ld.so man page. I used the LD_DEBUG variable to get full debugging
output:
LD_DEBUG=all ldd /opt/Navisphere/bin/naviagent 2>/root/ld.debug.log
linux-gate.so.1 => (0xffffe000)
libnsl.so.1 => /lib/libnsl.so.1 (0xf7fb7000)
libdl.so.2 => /lib/libdl.so.2 (0x00495000)
libm.so.6 => /lib/tls/libm.so.6 (0x0049b000)
libpthread.so.0 => /lib/tls/libpthread.so.0 (0x004ca000)
libc.so.6 => /lib/tls/libc.so.6 (0x00368000)
/lib/ld-linux.so.2 (0x0034f000)
The debug log is pretty big, so I attached it as a file. I looked
through it, but nothing looked unusual to me. Could be that I don't know
what to look for.
Any other ideas/suggestions?
