I tried to install Gentoo-2008.0 but everytime I tried to emerge something I got failure and message /usr/lib64/portage/bin/ebuild.sh line 1492 /bin/touch argument list too long. Reproducible: Always Steps to Reproduce: 1.emerge "something" 2. 3.
I think this is a duplicate of bug #222091. Look there first. Second, post your emerge --info and report back.
Apply the patch that's attached to bug 222091 for your current version of portage. *** This bug has been marked as a duplicate of bug 222091 ***
