when I emerge antlr (which apparently is a new dep for ant), I get the below message. I can emerge ant-core OK [ebuild N ] dev-java/antlr-2.7.3 [ebuild N ] dev-java/ant-tasks-1.6.2-r5 [ebuild U ] dev-java/ant-1.6.2-r6 [1.5.4-r1] Reproducible: Always Steps to Reproduce: 1.emerge antlr Actual Results: >>> Source unpacked. ./configure --prefix=/usr --host=i686-pc-linux-gnu --mandir=/usr/share/man --infodir=/usr/share/info --datadir=/usr/share --sysconfdir=/etc --localstatedir=/var/lib configure: WARNING: If you wanted to set the --build type, don't use --host.

I determined this was not an antlr problem, but rather the result of a bad symlink which was pointing to the older jre. changing /usr/local/bin/java to point to the new java fixed the problem.
