What you need to do is install LON-CAPA 2.10.0.RC2 on your VM, using  
the standard installation procedure.

See: http://install.loncapa.org/

There is a new link to instructions for Fedora 14 in the section:

"Installation on the following systems requires the use of a testing  
release of LON-CAPA.".

When you run ./install.pl as part of the pre-install you should call it using:

./install.pl --nodownload_loncapa

so the current production release (2.9.1) is not downloaded.

After ./install.pl has completed its operation you will download  
2.10.0.RC2 via:
wget http://install.lon-capa.org/versions/loncapa-2.10.0.RC2.tar.gz

Decompress that tarball and run ./UPDATE from within the  
loncapa-2.10.0.RC2 directory.

As part of the ./UPDATE process a tth.so (appropriate for your perl  
version and architecture) will be written to:


Once that is installed, when you next run make build, this error message:

**** ERROR **** neither source=../../modules/TexConvert/tthperl/tth.so ...

will no longer be displayed.

You will still see a warning:

> **** WARNING **** missing the file: ../../modules/TexConvert/tthperl/commands

but that will not be a problem, and make build will run to completion.  
  (Note: this WARNING can be eliminated if you also checkout the  
modules directory from the LON-CAPA CVS repository, but that is not  
necessary, if you already have a compiled tth.so in  

After "make build" is complete you will run "make install" (as root)  
to complete the update of the existing LON-CAPA installation on your
