Yes, I tried it around 2002/2003, back when the recommended way was from stage1. I think I had a P4 with HT. It was noticeably faster than redhat or mandrake (yes, I was distro hopping a lot). Emerge gnome-mono was a night run. Openoffice about 24hrs.
Lots of wasted time but I did learn how to setup some things manually.
Oh yeah, I remember those. My solution was to not emerge anything for 24 hours, by the next day usually they fixed the issue.
