Package: cl-portable-aserve Version: 1.2.42+cvs.2005.08.05-5 The main distribution of portable Aserve does not compile using MCL v5.0. The problem is in the file acl-compat/packages.lisp There is conditionalized code for (and mcl (not openmcl)) which performs a shadowing import of symbols into CCL. But SHADOWING- IMPORT is a function, not a macro. That means it needs to be wrapped in an EVAL-WHEN form, otherwise the import is not done at compile time and the subsequent DEFPACKAGE of gray-streams fails.
