As per summary, if you have two simulataneous emerge processes, their merge phases can conflict over the file /tmp/portage-prelink.tmp causing one emerge to fail out and possibly some corruption of content. The filename should have some emerge instance specific identifier in it, such as a process ID. Reproducible: Sometimes Steps to Reproduce: Reproduction is hard as it's all timing to cause it, and resource contention bugs like that are a pain to reproduce. Actual Results: Example error from the one emerge !!! Unable to copy file '/usr/lib/perl5/vendor_perl/5.8.2/i686- linux/Tk/pTk/tkUnixPort.h'. !!!
