digest not found after installing (cross-compiling)

[Justin Schneck <schneck.justin%gmail.com@localhost>]

I am trying to cross compile pkgsrc packages using an external
toolchain but I am encountering some errors when it first attempts to
build a patched libtool. The error I am getting is

It appears to install the package and clean up the work directory but
it stops here when trying to satisfy the dependency for digest.

Here is my mk.conf
