 I don't expect FreeBSD to adjust something which works to cater to 
 individual preferences, even if those preferences are mine.  :-)
 However, the way the UNAME environment variable is handled under the 
 ports is somewhat more prone to failure than, say, setting MAKE.  Even 
 if I export "MAKE=foobar", /usr/bin/make will override my setting with 
 something appropriate and the build works fine.

 The solution of unsetting UNAME is "good enough".  Setting UNAME in 
 /etc/make.conf, or for that matter, doing a "ln -s /usr/sbin/uname 
 /usr/local/bin/FreeBSD" would also work-- albeit the latter is even 
 more of a hack than overriding UNAME.
 However, it would be nice if /usr/ports/Mk/bsd.port.mk was smart enough 
 to test whether UNAME exists and is executable before trying to invoke 
 $UNAME as a program:
 # /bin/sh syntax
 if [ ! -x "$UNAME" ]; then
    export UNAME
 Also, I would suggest that the fact that $UNAME is significant to the 
 ports collection really ought to be mentioned in "man 7 ports".
 Thanks for your time and responses,
