User recently upgraded one of its servers to RHEL6 and installed Revo-Ent-6.2.0 with R 2.15.3 embedded in the tarball. Many of the R components that previously worked now produce errors. This includes:

· RODBC, which works for some users but not others
· RStudio Server, which no longer works with PAM authentication
