pkgs/development/libraries/slib/catalog-in-library-vicinity.patch

···
+Write the catalog in under `(library-vicinity)', which is a subdir of $out,
+rather than under `(implementation-vicinity)', which is a subdir of ${scheme}.
+
+The downside is that we can't build an SLIB for several Schemes at the
+same time.

+      SLIB is a portable library for the programming language Scheme.  It
+      provides a platform independent framework for using packages of Scheme
+      procedures and syntax.  As distributed, SLIB contains useful packages
+      for all Scheme implementations.  Its catalog can be transparently
+      extended to accomodate packages specific to a site, implementation,
+      user, or directory.
+
+      SLIB supports Bigloo, Chez, ELK 3.0, Gambit 4.0, Guile, JScheme, Kawa,
+      Larceny, MacScheme, MIT/GNU Scheme, Pocket Scheme, RScheme, scheme->C,
+      Scheme48, SCM, SCM Mac, scsh, sisc, Stk, T3.1, umb-scheme, and VSCM.
