[cl-cairo2-devel] issues with cl-cairo2 from asdf-install

[Peter Hildebrandt]

Tamas,

thanks for getting back to me.  I had postponed the cffi upgrade,
because it breaks cells-gtk.  I guess the time has come and I have to
figure out how to change those typedefs.

Anyway, asdf-install failed around the my-double-type form.  I created
a quick fix with #+sbcl features.  The attached patch also contains
additions for the library names on ubuntu 8.04 (name.so.X instead of
name.so).

Thanks again,
Peter
