No problems running the ./autogen.sh script? Some folks seem to
have a very difficult time getting past that step.

Hmmm, you didn't accidentally set a memory limit with the shell's
"limit" command did you? Something like "limit data 16m" would
cause a problem.

That structure is not huge so the memory allocation limit must have
been reached earlier for an unknown reason.

It could be part of the problem - the latest version of mpeg2enc
does have a shared library now.
Thing to try is doing the make install to get all the new .a and .so
and .h files installed. Then do a make clean and make again - I still
have the nagging feeling that during a build the previously installed
files can be consulted/used (depending on the compiler and the order of
the -I and -L flags used).
Good Luck!
