It appears to be possible; I checked in a change to do that, on Linux
systems.

It worked when I tried it on my Debian 2.1 partition - I installed
UCD SNMP 4.0.1 built with "--enable-shared" (and the "configure" script
tweaked with a change from the 4.1.1 script, so that it uses the correct
commands, on Linux, to build the shared library), and configured and
built Ethereal, and the resulting binary worked both with the 4.0.1
shared library and the 4.1.1 shared library.
