Bugzilla Bug 70135

when emerging libungif-4.1.0.1b with the 'maketest' FEATURE enabled, the emerge
will fail if the xv package is not installed.  libungif uses xv to produce
images which open in a series of windows.  without the xv package the result is
this:

make  check-TESTS
make[2]: Entering directory
`/var/tmp/portage/libungif-4.1.0.1b/work/libungif-4.1.0b1'

disabling maketest or emerging the xv package before libungif results in a
successful install.

Reproducible: Always
Steps to Reproduce:
1. emerge libungif-4.1.0.1b with makecheck in FEATURES and without xv installed
2. emerge fails
3. emerge xv then emerge libungif

Actual Results:  
Failed install.

Expected Results:  
Install successfully.

if possible, adding the xv dependancy if maketest is enabled to the ebuild
could
solve the problem - but i leave that to someone who knows what they're doing.
;)

usasa, your the last to bump this one.. assigning to you

Hi, thanks for the bug report. I disabled make check if
xv is not installed. We cannot modify DEPEND list inside
ebuilds unless we use USE flags (FEATURES is not handled
like USE flags). I added ewarns to install xv if you wants
to run maketest for this package. Hope this will help.
