This appears to be a regression which first appeared in webkit-gtk-2.6.4.ebuild. All previous versions have this test before the check-reqs_* calls in both pkg_pretend and pkg_setup: if [[ ${MERGE_TYPE} != "binary" ]] && is-flagq "-g*" && ! is-flagq "-g*0" ; then Obviously this ensures that we only check for the massive 18GB disk requirement if the user has debug flags. However starting with 2.6.4, the above test was reverted back to just: if [[ ${MERGE_TYPE} != "binary" ]] ; then So any source build claims to require 18G. Please re-add the check for debug flags so not everyone sees this warning. Thanks!
I fixed this two days ago while working on bug #555374; I didn't see that you had also noticed the same problem.
