Yes, like all documentation it becomes out-of-date, but this one is
especially dated. I don't get much help, have very limited time, and
have had higher priorities. Please refer also to the more up-to-date
API reference generated by Doxygen (something I did put a fair amount
of work into last year) - perhaps start with the Data Structures tab.
It has been my intention to fold most of this old, explanatory docs
into the header files as Doxygen docs while updating and improving it
at the same time.

It is no longer a build issue. You would not be able to run it if so.
You did not (successfully) run 'make install' from the mlt source
directory, or you did not tell it where to find the plugins. If you do
not want to install, then you can set the MLT_REPOSITORY environment
variable or run 'source setenv' from the top-level of the mlt source
tree to let a bash script set it for you along with other helpful
environment variables.
