596<p>
597<c>compaq-jre</c> and <c>compaq-jdk</c> are not very desirable because they are
598unsupported upstream and obsolete. They only provide Java 1.3.1 and are binary
599only. The binaries are compiled against an older glibc which causes some
600unexpected results when you are using a recent glibc. See <uri
601link="https://bugs.gentoo.org/84306">bug #84306</uri> for our attempts at
602workarounds.

751This is usually caused by a bad -mcpu setting. For example, the AlphaServer
752800 needs to be compiled with the <c>ev5</c> flag for xorg <b>and</b> glibc.
753Failing to do so will cause undesired results.
