My understanding is that you created a dependency specification that is
only accidently satisfied.  You asked textproc/flex to be installed, but
then check /usr/bin/flex from that package (which is not inside).

Flex is notorious.  If flex is specified in BUILD_DEPENDS, then 100% of
the time, you really, really want /usr/local/bin/flex.  If /usr/bin/flex
works, then you would not put it in BUILD_DEPENDS.  /usr/bin/flex is
available on all releases so if it works as you say, then textproc/flex
will never get pulled in.

My guess is that if textproc/flex is listed here, then it's needed over
the base flex.  Thus, I think the change is an error.
