George,
On our AIX system, lex is in /usr/bin/lex.
Chances are you probably won't ever use ictrans, so I wouldn't worry too much about this.
Did a $NCARG_ROOT/bin/ncl file get created? If so, then you have successfully built "ncl".
If you really want to get ictrans built, you can try the attached lex.yy.c, which is what lex generated on my AIX machine.
Put the file in $NCARG/ncarview/src/lib/libictrans, and then type:
cd $NCARG
make all install
