[Dovecot] rc17 Linux RPM distribution rebuild trouble.

[Serge D]

   The question is addressed to Linux RPM-packagers.

Hello!

   I was trying to rebuild rc17 binaries from 
dovecot-1.0-1_38.rc17.at.src.rpm
taken at  ATrpms <http://ATrpms.net/>.  The process fails with following 
messages:
--------------------
Making install in imap-quota
make[3]: Entering directory 
`/usr/src/asplinux/BUILD/dovecot-1.0.rc15/src/plugins/imap-quota'
make[4]: Entering directory 
`/usr/src/asplinux/BUILD/dovecot-1.0.rc15/src/plugins/imap-quota'
make[4]: Target `install-exec-am' does not require perform any command.
test -z "/usr/lib/dovecot/imap" || mkdir -p -- 
"/var/tmp/dovecot-1.0-0_34.rc15-root/usr/lib/dovecot/imap"
mkdir: `/var/tmp/dovecot-1.0-0_34.rc15-root/usr/lib/dovecot/imap' 
exists, but it is not a directory
make[4]: *** [install-imap_moduleLTLIBRARIES] Error 1
-------------------
     As I have not so much experience at RPM-packaging, so would be 
thankful for the ideas how to fix it?

   Kind regards,
   - Serge.
