--- Comment #70 from Roland Haeder roland@mxchange.org 2010-07-30 00:46:51 --- I found a workaround for the missing sound:
I have downloaded the 32-bit version of libopenal and libopenal-dev, extracted both manually, put all from /usr/lib into /usr/lib32, set a symbolic link from libopenal.so.1 to libopenal.so (very important step!) in /usr/lib32, edited the package information file openal.pkg (libdir=/usr/lib32) and configure was no longer complaining about missing libopenal 32-bit development files. :-)
So let's hope this works...
