First, for using RDBC with a MySQL backend you need to install:

       MySQL client libraries

It is likely that the first three are already packaged for your Linux
distribution so you may only need to build RDBC.  RDBC uses the
env. var. UNIXODBC_DIR to find unixODBC.  It would be set to "/usr" if
you installed from system packages.

Second, ROOT is independent from RDBC and RDBC doesn't need to be, nor
should it be, installed in $ROOTSYS, so I can't see how installing
"ODBC stuff" can effect normal ROOT usage.  My guess is your ROOT
installation proper has some other problem.

In case it wasn't obvious, that page contains instructions for how
MINOS collaborators should install this "ODBC stuff" for running the
MINOS offline software.  There was no attempt to make it generic.  It
may indeed be useful to others, but only by accident.

ROOT proper knows nothing of RDBC
