Judging from the message, I'd say you were using /bin/csh (the Bourne shell,
/bin/sh would simply say "not found"). Anyway, the C shell uses command
hashing. In short, it searches for all executables in the path, and builds
a hash table for finding the command. If you change your path, this table
is rebuilt automatically, as it is on login. Anyway, the short answer to
your question is, run the 'rehash' command at the prompt, to rebuild the
hash table. Hope this helps...
