Confirmed,

  Libtool version mismatch resulting in undeclared 'to_tool_file_cmd' is common
to all tde modules requiring autoconf. With tdeaddons, after issuing:

  autoreconf --force --install

to get past the initial libtool version mismatch, the build again failed with:

libtool: compile:  g++ -DHAVE_CONFIG_H -I. -I../../.. -I/opt/trinity/include
-I/opt/tqt3/include -I. -include tqt.h -I/opt/trinity/include/tde
-DQT_THREAD_SUPPORT -D_REENTRANT -Wno-long-long -Wundef -ansi

-fPIC -DPIC -o .libs/geo_xxport.o

g++: error: : No such file or directory
g++: fatal error: no input files

Note the empty filename:

.deps/geo_xxport.Tpo -c ""  -fPIC -DPIC -o .libs/geo_xxport.o
                      ^^^^^^

  So here is our third point in the line. I've updated
http://bugs.pearsoncomputing.net/show_bug.cgi?id=924 with the new information.

  Additionally, I have additional work to do on tdeaddons. After sorting the
libtool issue, I ran into:

geo_xxport.cpp:114:26: fatal error: geo_xxport.moc: No such file or directory
compilation terminated.

  So there is something going on there I don't quite understand...
