[Evolution] Problem building source rpm

[Adam Williams <awilliam whitemice org>]

I'm having a problem building the evo source rpms (I want to take
another whack at building evo --with-krb5).  But to build evo requires
evo-db3 (apparently),  but building evo-db3 dies....

rpm --rebuild evo-db3-3.1.17-ximian.2.src.rpm
. . . . 
creating db.h
creating db_int.h
creating db_185.h
creating db_config.h
+ '[' / '!=' /var/tmp/evo-db3-3.1.17-root ']'
+ rm -rf /var/tmp/evo-db3-3.1.17-root
+ cd build_unix
/var/tmp/rpm-tmp.1466: cd: build_unix: No such file or directory
error: Bad exit status from /var/tmp/rpm-tmp.1466 (%build)
RPM build errors:
    Bad exit status from /var/tmp/rpm-tmp.1466 (%build)

Any tips?
