brew doctor  
===========

ein-2:ditz-commander_0.4.orig john$ brew doctor
Some keg-only formula are linked into the Cellar.

Linking a keg-only formula, such as gettext, into the cellar with
`brew link f` will cause other formulae to detect them during the
`./configure` step. This may cause problems when compiling those
other formulae.

Binaries provided by keg-only formulae may override system binaries
with other strange results.

You may wish to `brew unlink` these brews:
    libxml2
