It would be useful if all lisp interpreters provided a virtual package (such as "common-lisp") that could be used as a dependency for lisp packages that are portable across implementations.

For example, cl-ppcre currently has two instances in the AUR: one that depends on "clisp", the other on "sbcl". They could be replaced with a single package that depends on "common-lisp" if the clisp and sbcl packages both provided the virtual "common-lisp" package.

This is easily done by adding a 'provides' line in the PKGBUILDs of all lisp interpreters: "provides=('common-lisp')"

I think the affected packages are clisp, sbcl, cmucl and ecl.

See the Lisp Package Guidelines on the wiki: http://wiki.archlinux.org/index.php/Lisp_Package_Guidelines.

Thank you!
