i looked into this once and i think the answer is 'dont even bother' it died horribly for me on newer glibc/gcc systems ... and the fact that it hasnt be updated in YEARS should be enough to make you want to use valgrind in other words, i vote to close this bug as UPSTREAM and just tell users to use valgrind ;)
maybe this should be completly removed from portage tree
I think it's still useful to have it in the tree for systems where it does work. I agree with Spanky though that we should close it as UPSTREAM since there's really not much we can do about it. I'm going to go ahead and do just that as a matter of fact. We can use this bug as a metabug for future efence bugs if necessary.
