Hi -

I just tried to load the latest CFFI from darcs into CCL 1.2, and I got a symbol conflict between CCL:COPY-FILE and ALEXANDRIA.0.DEV:COPY- FILE:

CL-USER> (asdf:oos 'asdf:load-op :cffi) ; loading system definition from /Users/dkatz/dev/lisp/libs/clbuild/ systems/cffi.asd into #<Package "ASDF0"> ; registering #<SYSTEM CFFI #x8754B3E> as CFFI ; loading system definition from /Users/dkatz/dev/lisp/libs/clbuild/ systems/babel.asd into #<Package "ASDF0"> ; registering #<SYSTEM BABEL #x87910EE> as BABEL ; loading system definition from /Users/dkatz/dev/lisp/libs/clbuild/ systems/alexandria.asd into #<Package "ASDF0"> ; registering #<SYSTEM :ALEXANDRIA #x87BA8B6> as ALEXANDRIA ; loading system definition from /Users/dkatz/dev/lisp/libs/clbuild/ systems/trivial-features.asd into #<Package "ASDF0"> ; registering #<SYSTEM TRIVIAL-FEATURES #x86F53D6> as TRIVIAL-FEATURES

Using #<Package "CCL"> in #<Package "CFFI-SYS"> would cause name conflicts with symbols inherited by that package: ALEXANDRIA.0.DEV:COPY-FILE COPY-FILE

'NIL)

When I look in the CFFI code, the problem seems to come from cffi-- openmcl.lisp where ALEXANDRIA and CCL are both being :use-d without any shadowing. As far as I can tell, there are no calls to either COPY-FILE function anywhere in the CFFI code, so it seems to me that choosing one of these functions to shadow the other should be a simple affair since it shouldn't matter at all which one is chosen..

Would it be possible to get this fixed?

Thanks.
