Description of problem:
Attempting to build an RPM in the environment where CDPATH is set makes cp
function in a way that breaks the build, because cd tries to find the path in
the CDPATH. If I unset the CDPATH variable the build works correctly.

Just set the package name that is not in the SCMROOT. My setup below.

Version-Release number of selected component (if applicable):
rpm-4.4.2.2-7.fc8
rpmrebuild-2.1.1-9.fc8


How reproducible:
Always

### be sure to have CDPATH set
[dkovalsk@kovinek ~]$ echo $CDPATH
/home/dkovalsk/SCM

### relevant part of the specfile (only the prep section)
%prep
echo SETUP1 - `pwd`
ls -l |head
%setup -q -n Django
echo SETUP2 - `pwd`
ls -l


### my SCMROOT, note there's no Django with capital 'D'
[dkovalsk@kovinek ~]$ ls -l /home/dkovalsk/SCM/|grep -i dj
lrwxrwxrwx  1 dkovalsk dkovalsk   11 2007-10-07 20:10 django -> SVN/django/
lrwxrwxrwx  1 dkovalsk dkovalsk   14 2007-10-07 20:10 django-dk -> GIT/django-dk/


### Now the build fails:

exit 0



If I add `ls -l | head' to line 34 -> the files are there.
