I notice another thing about when the
errors begin to cascade;
the ps command fails also momentarily,
then works again!
Here is what I could see in two terminal windows;
the first was running the command
"./configure --with-perl=/usr/bin/perl
--enable-shared"
in /usr/local/src/ImageMagick-5.5.6
the second was running "ps -af" from time to time.
Notice that ps fails.
First terminal output:
checking for gs mono device... pbmraw
checking for gs PDF writing device... pdfwrite
checking for gs PS writing device... pswrite
checking for gs EPS writing device... epswrite
checking for perl... /usr/bin/perl

Ah ha!
Any suggestions?
Also, interestingly enough, later ps works fine!
But there are other
problems that lead me to rebooting,
like can not start new applications.
