--------------------------------------+-------------------------------------
 php5 has +apache2 in the default_variants, which add a dependency on
 apache2. This means, anyone who installs php5 is required to installed
 apache2 as well.

 The swig port offers language bindings for several ports using variants,
 including php5. It has +php5 in the default_variants.

 So, installing swig also installs apache2 by default. This is not very
 nice to the user as apache2 is not lightweight. Also, this can happen if
 the user actually needs swig for e.g. python bindings.

 Can we please either remove the default +apache2 from php5 or the default
 +php5 from swig?
