Comment (by ryandesign):

 To reproduce, install the ccache port, set `configureccache yes` in
 macports.conf, build the ocaml port from source, then try to build the
 ocaml-bigstringaf port from source.

 There are tons of files installed by the ocaml port that contain the fact
 that ccache was used to build the port:

 This doesn't happen if ccache is not used when building ocaml (e.g. when
 installing a binary of ocaml from our server).

 So there are two problems that need to be fixed.

 1. The ocaml port should excise all of these references to ccache from the
 installed files.
 2. The ocaml-bigstringaf port, and perhaps all ports that use ocaml, need
 to build using the compiler MacPorts tells them to build with, not the
 compiler that ocaml was built with.
