I don't have time just now for testing this, but here are some side-comments,
not central to your problem, but which you might find generally useful.

The error messages are awful and ugly, but do they matter? Do
emacs-w3m / flim / apel compile anyway? Do they work despite the error
messages? If they do work, what functionality is missing?

If you're using bash or similar shell, you can condense the six 'mkdir's
into a single command:

  mkdir -p ~/.emacs.d/{src,lisp/{apel,flim,emacs-w3m}}

The two 'git clone' commands, as written, will pull entire repositories,
including all historical artifacts of all possible git branches, none of
which you need. A handy general alternative is:

  git clone --depth=1 --branch=master <repository-url>

For github, one may also generally perform direct downloads of
repository snapshots, without any git overhead whatsoever, by replacing
the ".git" suffix of the url with either "archive/master.tar.gz" or

  repo="<repository-url>"  wget -c ${repo/%.git/\/archive\/master.tar.gz} -O - | tar -xz

I don't look kindly upon the three 'find -exec cp' commands, because
they exclude documentation and other file that could be useful in the
future. Furthermore, some packages have a legal licensing requirement to
include certain files (eg. LICENSE, AUTHORS)[IANAL]. If you choose for your
recipe to perform some form of 'git clone', an alternative would be to
'rm -r .git'; if you for your recipe to perform a snapshot download, you
won't have overhead to exclude.

Finally, your recipe doesn't delete its temporary files:

  rm -r ~/.emacs.d/src/{apel,flim,emacs-w3m}

In my example, I could bring myself to delete from "src" because a user
might have other unrelated directories already there...
