revision properties

[kfsone]

I want our automated build process (using FinalBuilder) to mark
whether revisions built or failed. I'm doing

 svn --username BLAH --password BLAH propset -r 408 --revprop fb:pc-
build ok

I get back:

svn: DAV request failed; it's possible that the repository's pre-
revprop-change hook either failed or is non-existent
svn: At least one property change failed; repository is unchanged
svn: Error setting property 'fb:pc-build':
could not remove a property

Subversion 1.5.3 r33570
VisualSVN Server 1.5.4 and 1.6.1

So I created a hook a quick starter:

   #!/usr/bin/env perl

   print "Property value is supplied via STDIN:\n" ;
   while (<STDIN>)
   {
     chomp ; print STDERR "[ $_ ]\n" ;
   }
   print STDERR "But I'm not accepting revprop changes just now\n" ;
   exit 1 ;

But nothing is delivered on STDIN.
