We have that in our list of things to do; however you can always get the
code from cvs as well. That would avoid the RPM issue.

It looks to me like the configure script is detecting you have quickcam
support. That would happen if you have /usr/local/lib/libqcam.a, or
/dev/qcam0, or have specifically specified the directory for the code (which
I'm guessing you didn't do).

Why don't you try reconfiguring using something like --without-qcam to
explicitly disabling this?  Does slackware include the libraries? RedHat
doesn't, this sounds more like a porting issue than a mistake in our cvs
stuff.  Note, our build system is designed for RedHat and Windows, however
we're happy to modify it to include slackware, if you tell us what needs to
be done...
