Can't produce output

["K. Richard Pixley" <rich noir com>]

I'm trying to produce rpm's and, of course, can't because the default
output directory isn't writable by me.

The only way I can find to set the output directory is via "macros",
though I can't seem to find any documentation on the macro file format,
existing macros, or the like.  Is there any?

Or can someone tell me what's wrong with this approach?

--rich

echo '%_rpmdir\t'`pwd` > rpm-macros
rpmbuild --macros=rpm-macros -bb -vv peakstream.spec
[...]
error: Could not open /usr/src/redhat/RPMS/i386/peakstream-0-0.i386.rpm:
