Bugzilla Bug 207415

dev-util/kdevelop-3.5.0 depends on:

cvs? ( || ( kde-base/kdesdk kde-base/cervisia ))
subversion? ( || ( kde-base/kdesdk kde-base/kdesdk-kioslaves ))

if i have installed kde-base/kdesdk-kioslaves and not installed
kde-base/cervisia, and try install 

# USE="cvs subversion" emerge -pv kdevelop 

I give circular block of kde-base/kdesdk and kde-base/kdesdk-kioslaves

Reproducible: Always

Steps to Reproduce:
1. emerge kde-base/kdesdk-kioslaves
2. remove kde-base/cervisia if installed
3. USE="cvs subversion" emerge -pv kdevelop 

Actual Results:  
[ebuild  N    ] kde-base/kdesdk-3.5.8  USE="berkdb subversion -arts -debug
-kdeenablefinal -kdehiddenvisibility -xinerama"
[ebuild  N    ] dev-util/kdevelop-3.5.0  USE="cvs fortran haskell pascal perl
php python ruby sql subversion -ada -arts -clearcase -debug -java -perforce
-xinerama"
[blocks B     ] =kde-base/kdesdk-kioslaves-3.5* (is blocking
kde-base/kdesdk-3.5.8)
[blocks B     ] =kde-base/kdesdk-3.5* (is blocking
kde-base/kdesdk-kioslaves-3.5.8)


Expected Results:  
...
[ebuild  N    ] kde-base/cervisia-3.5.8  USE="-arts -debug -kdeenablefinal
-kdehiddenvisibility -xinerama"
[ebuild  N    ] dev-util/kdevelop-3.5.0  USE="cvs fortran haskell pascal perl
php python ruby sql subversion -ada -arts -clearcase -debug -java -perforce
-xinerama"

if i change order from:

cvs? ( || ( kde-base/kdesdk kde-base/cervisia ))
subversion? ( || ( kde-base/kdesdk kde-base/kdesdk-kioslaves ))

to:

cvs? ( || ( kde-base/cervisia kde-base/kdesdk ))
subversion? ( || ( kde-base/kdesdk-kioslaves kde-base/kdesdk  ))

emerging works as expected.
