Bugzilla Bug 111455

This is a bug to record a dependency issue, that might be solveable in the
future.  I experience this problem on both x86 and ppc-macos.

The problem is as follows:

# env USE="gif rle" emerge -pv urt

These are the packages that I would merge, in order:

Calculating dependencies ...done!
[ebuild  N    ] media-libs/giflib-4.1.4  -X +rle 0 kB 
[ebuild  N    ] media-libs/urt-3.1b-r1  -X +gif -gs +tiff 0 kB 

Total size of downloads: 0 kB


So, urt pulls giflib, and giflib on it's turn needs urt.  I enabled rle USE-flag.

then compiling (by invoking the same command minus "-pv", fails in giflib:

First emerging urt (without rle USE-flag) then reemerging giflib with rle USE
flag works, since urt probably provides rle.

Reproducible: Always
Steps to Reproduce:
1. make sure giflib and urt are not emerged
2. env USE="gif rle" emerge urt
3. watch compilation of giflib die on rle

Actual Results:  
compilation of giflib failed due to missing rle

Expected Results:  
ideally, portage should detect it and compile giflib twice, once without rle and
once with after urt has compiled.

Circular dependencies are certainly bad... Looks like vapier introduced this in
Bug 107497 (and it does not seem to fix the original problem anyway)...

Ah, I missed that bug.

it fixes the problem just fine, you're confusing issues jakub

fixed *this* issue in cvs
