Thank You then....

Look for lex on your server and make sure its in your PATH variable.

bash$>locate lex

Actually, I ran into the same problem.

I just did a search using rpmdrake for lex and found flex.

It worked after that.

In RedHat, just install flex and everything will work.

flex-2.5.4a-15.i386.rpm
