Dirk,

You need to use the special "Red Hat 6" version of J/Link. This was
very poorly named--it is really for all Linuxes with glibc2.1 and
later, which basically means all recent Linux distributions.

This version of J/Link has the native library already compiled against
a special version of the MathLink library for glibc2.1.
