Thank you for this detailed reply. I always like to read your really very
informative contributions to the gentoo mailing lists. As to your questions I
cannot tell what the versions of bash portage etc. were. I emerged glibc
during my migration from the 2004.3 profile to the 2005.0 profile which is
now complete. During the migration new versions of bash, portage and so an
were merged. Now all is new and works! I cannot reproduce the loop. What
happened was, that the emerge of glibc started to loop at a certain point. I
then killed the emerge, issued the same command again and the merge started
to loop at another point. I'll let MAKEOPTS set and observe what happens in
Thanks to all who answered.
