This may be a dupe of Bug #38874
It definitely doesn't look like a dupe of that bug to me. I don't even think that they are the same package. The problems are similar in cause, however, since missing jars lead to missing classes, but unlike that other bug, the ebuild completely fails here. Also, this is the 'ant' package not the 'ant-optional' package.
That bug was indeed referring to ant-optional, however I got the same error when trying to re-emerge ant once it was already installed. I was able to fix with: # java-config --clean-system-classpath # env-update && source /etc/profile # emerge ant
ant-1.6.0 is going into package.mask for now. Too many problems & the tree needs to be tested against it. Please merge 1.5.4. We cannot support 1.6.0 yet. If you want to use 1.6.0 on your own, download it, then put the distributables somewhere on your system, and update your CLASSPATH via java-config so that your desired version of ant takes precedence over 1.5.4.
Fixed in the new ant 1.6.1, try it out, it just got unmasked :)
