Bugzilla Bug 64550

The "configure" script used by scummvm tests for the presence of libmpeg2 (and
the need for memory alignment) by compiling a test object at the hard-wired
path "/tmp/scummvm-conf". On systems where /tmp is on a partition without
execution permissions, the test fails and libmpeg2 is never detected. Beginning
of emerge output:

Calculating dependencies ...done!

Reproducible: Always
Steps to Reproduce:
1. Remove execute permissions on partition containing /tmp (mount -o
remount,noexec). (Kids without a separate /tmp partition, don't try this at
home.)
2. emerge games-engines/scummvm-0.6.1b

Actual Results:  
libmpeg2 was not detected.

Expected Results:  
libmpeg2 should have been detected.

Created an attachment (id=39868) [edit]
modified scummvm-0.6.1b.ebuild

This modified ebuild points the configure script to the build directory for
making test objects.

Created an attachment (id=39869) [edit]
patch to configure script, instead

On second thought, why not just patch the configure script to build in its
current directory?

no end of ugly autotools stuff out there I guess.

Fixed in CVS.  resync and remerge.  Thanks for the bug report.
