jdbc redhat 6.0 make problem

Hello,

This is my first attempt at installing jdbc on a rehat box. I have
installed postgres-6.4.2 and jdbc on slakware 3.6 many times and I have
automated the install process. I am using the same install process on
the redhat box and it fails when running make.

java.lang.NoClassDefFoundError: sun/tools/jar/Main
at java.lang.Throwable.<init>(Throwable.java:40)
at java.lang.Error.<init>(Error.java:21)
at java.lang.LinkageError.<init>(LinkageError.java:21)
at
java.lang.NoClassDefFoundError.<init>(NoClassDefFoundError.java:21)

My profile (CLASSPATH etc .. ) and install process is the same on both
slakware-3.6 and Redhat-6.0 boxes, so I assume the problem has to do
with some difference in the distribution and not my install procedure.

Where should I start looking to resolve this ?

Any help would be appreciated.
