"cvs commit: cannot exec :local:"

[Euan Guttridge]

I am trying to run a script on each commit (to lock certain branches). I get
the error below. My entries in commitinfo and checkoutlist are below. Any
advice appreciated. CVS 1.11.2, RH9.

Thanks
Euan

cvs commit: cannot exec
:local:/home/cvs/MYRepository/CVSROOT/precommit_check: No such file or
directory
cvs commit: Pre-commit check failed
cvs [commit aborted]: correct above errors first!


CVSROOT/commitinfo:
DEFAULT $CVSROOT/CVSROOT/precommit_check

CVSROOT/checkoutlist:
 precommit_check cannot find precommit_check file

CVSROOT/precommit_check
