Description of problem:
[root@withywindle ~]# rpm -e xml-commons-apis
/var/tmp/rpm-tmp.64595: line 1: /usr/bin/rebuild-gcj-db: No such file or directory
error: %postun(xml-commons-apis-1.0-0.b2.7jpp_3fc.i386) scriptlet failed, exit
status 127
[root@withywindle ~]# rpm -q xml-commons-apis
xml-commons-apis-1.0-0.b2.7jpp_3fc



Either a Requires is missing or the postun scriptlet should check to see whether
/usr/bin/rebuild-gcj-db exists
