Thanks for that comment. I had left compression disabled because I was
worried about the time requirement. On your tip, I added the same line to
.cshrc.extensions.

Huh. The above line is not present in the installed
/usr/local/share/doc/ccache/ccache-howto-freebsd.txt file on my system. Maybe
I should reinstall devel/ccache to see if an updated, corrected version
appears?

In the line above, everything before the "&&" is missing in the doc file.

In the line above, the pluses are not escaped in the installed doc file.

And the two .endif lines are also missing in the doc file.
I replaced the three lines in my /etc/make.conf with the lines you show
above, and now it all works beautifully. Thank you very, very much.

I'm running 10.1-STABLE.

Oh, good grief! I apologize most profusely for the typo, Warren. I don't
know why I typed that, but will chalk it up to yet another of my infamous
posting-hours-past-my-bedtime brain farts. Sigh. :-(
Thanks again, though.
