[gentoo-dev] Installing python add-on stuff..

[Jonas Berlin]

I have a package providing a .py and a .so file.

When and how should I install these ?

I was thinking of something like this, copying ideas from elsewhere:

  DEPEND="... python? (dev-lang/python) ..."

Should this maybe be sys-devel/spython instead ? Should spython be
unmerged if python is merged ?

Then, in the install part:

  src_install() {
    ..
    if [ "use python" ] ; then
      insinto /usr/lib/python2.0
      doins snack.py
	    
      insinto /usr/lib/python2.0/lib-dynload
      doins _snackmodule.so
    fi
    ..
  }

Now I noticed the .py files already in /usr/lib/python2.0/ also have .pyc
and .pyo files with the same name, so I guess they are some kind of
precompiled files.

I found a command like this in some rpm spec file:

  python -c 'from compileall import *; \
  compile_dir("'$RPM_BUILD_ROOT'/usr/lib/python2.0",10,"/usr/lib/python2.0")'

I would guess this could create the .pyc and .pyo files. Now I don't know
the behaviour of this command, but it would seem like this command would
install stuff from $RPM_BUILD_ROOT/usr/lib/python2.0 to /usr/lib/python2.0,
so this command might not be directly suitable for my need. And what's the
"10" in the parameter list?

Also, how about the version number? Should I do

  pythondir=/usr/lib/python`(python -V 2>&1)|sed 's/[^0-9.]//g'`

to get the correct installation location ?
