I installed cvszilla by exec "perl install.pl" and it finished
without error. But when I edited the files in CVSROOT and tried to
commit them to the CVS ,it prompted as these:

Uncaught exception from user code:
Base class package "Class::DBI" is empty.

package first.) at /usr/share/cvszilla/bin/cvsdb/DBI.pm line 3
