Description:

PyPy uses cffi module to interact with low level c libraries in many modules, many of which require compilation of c source given in python files. This compilation can either take place at compile time if the libraries/headers are found or at runtime. However, compiling at runtime requires writing permission to system path which is not possible for non-root users and therefore should not be used for packaging.

Currently the pypy(3) packages miss a lot of make dependencies which makes a lot of pypy modules not usable for non-root users (to see the problem, just import these modules as non-root). The list of affected modules and the corresponding libraries are:

curses module: ncurses
sqlite3 module: sqlite
gdbm module: gdbm
lib-tk modules (e.g. Tkinter): tk and tcl

The problem should be fixed by adding these modules to make depends.
They should also be added to optdepends.
