You haven't really attributed the functions you use to particular

The solutions are simple:
1) Compile R yourself -- the best choice.

This is a problem with coda's mcmc summary method. I suspect it is in

For your immediate purposes you could extract the posterior density

mdbtools claims to have an ODBC driver, so no conversion should be
