Following Chris Jones fiancee's example, I did a "rm -R
/usr/include" and then then reinstalled base.tgz and comp.tgz.

  (FWIW, I first tried "tar dzpf comp.tgz -C /" before actually
   unpacking the file just to see if there were any differences
   between my /usr/include and the one in the file, and none were
   noted. So I have no idea why reinstalling these distribution sets
   did anything.)

 After doing this, I had a bit more success this time around with the
php3-mysql package.

I switched into that directory, did a "make clean", and then "make &&
make install".  This time it got as far as installing everything
before hitting a bunch of very strange errors:

install -c -o root -g wheel -m 444 /usr/local/home/czyz/pkgsrc/www/php3-mysql/work/php-3.0.7/functions/mysql.so /usr/pkg/lib/php3/

Well, I then did a "setenv FORCE_PKG_REGISTER" and a "make reinstall"
and installation finished. I have no idea why I had to reinstall any
distribution sets or any fancy acrobatics to get this installed, but
it looks like the job is done.

Hmmm, perhaps I shouldn't be overclocking my Celeron...
