It is indeed set to -lc_r, and the fourth line down below this does show
that -lc_r is being used.  But apparently not for the making of
libMagic.la.

I don't know much if anything about libtool. But will give it atleast a
glance.

I didn't think it was a libkse issue. In thinking that it might be a bad
port cvsup, I rm -rf'd ports and recvsup'd from cvsup.freebsd.org, and
had encountered the same issue. Ruling out a local ports modification
issue (that and another poster had said he got the same error with his
threaded ImageMagick build).
