That's the first anyone's mentioned that type of problem. Usually
the problems center around the having the other software (libdv,
libquicktime, libSDL, and so on) installed or meeting the
minimum reqired versions of autoconf, automake and libtool.

Interesting - I didn't realize "versioned symbols" were being used.

No sense in trying to run the program later on - the library wasn't
created or is not usable due to the undefined symbol error above.
Hmmm, that's out of the C++ runtime libs though. Possible there's
a problem building with C++ 2.95.4 I suppose.

Makes sense - I think the library didn't get created because the
linker bailed out when the undefined symbol error happened.
A little more info is probably going to be needed. What distribution
or system is currently using 2.95.4 rather than 3.3.x (even OSX 10.3
which is a year old now has g++/gcc 3.3)? Although I don't think it's
the cause of the problem there is a chance that libtool is involved -
what version of libtool is being used?
So far on the SuSE 9.2 systems there haven't been any problems
building mjpegtools. OS/X builds and runs fine too (there's a buglet
when using multiple threads that's being investigated but -M0 is the
workaround for now).
The other question (as an aside) is how was the DTS file created? Is
there a free DTS encoder available? Last time I (briefly) looked at
DTS the only encoders I saw were very expensive commercial ones.
