Do you have a different version installed on the system while you're
trying to run from the build directory? I've run into problems in the
past with that. The RUN_FROM_BUILD_DIRECTORY logic in epan/filesystem.c
doesn't seem to have anything to do with dynamic library linking and it
turns itself on automatically when the executable name has ".libs" at
the beginning anyway.

FreeBSD has a tool called ldd that links the objects that an executable
is linked to. Linux should have a similar program. What about if you
run it with "libtool --mode=execute" like below:

sfisher@shadow:/usr/local/src/wireshark>libtool --mode=execute ldd ./tshark
/usr/local/src/wireshark/.libs/tshark:
        libwiretap.so.0 => /usr/local/src/wireshark/wiretap/.libs/libwiretap.so.0 (0x280ba000)
        libwireshark.so.0 => /usr/local/src/wireshark/epan/.libs/libwireshark.so.0 (0x28108000)
        libwsutil.so.0 => /usr/local/src/wireshark/wsutil/.libs/libwsutil.so.0 (0x2a272000)
  <snip>

When I don't run with the wrapper, it finds the installed libraries:

sfisher@shadow:/usr/local/src/wireshark>libtool --mode=execute ldd .libs/tshark
.libs/tshark:
        libwiretap.so.0 => /usr/local/lib/libwiretap.so.0 (0x280ba000)
        libwireshark.so.0 => /usr/local/lib/libwireshark.so.0 (0x28108000)
        libwsutil.so.0 => /usr/local/lib/libwsutil.so.0 (0x2a272000)
  <snip>
