+# sci-mathematics/isabelle requires sci-mathematics/sha1-polyml, to avoid

+# ### load_lib </usr/bin/libsha1.so> : /usr/bin/libsha1.so: cannot open shared
+#  object file: No such file or directory
+# ### Using slow ML implementation of SHA1.digest
+# sci-mathematics/sha1-polyml supplies the library libsha1.so.  Which
+# is the implementation of SHA1 taken from the GNU coreutils package
+# as described in the sci-mathematics/sha1-polyml README.  Isabelle
+# builds libsha1.so in the contrib/polyml/$ML_PLATFORM directory.
+# isabelle dynamically loads libsha1.so as a plugin.  The Isabelle-2012
+# linux binary bundle places libsha1.so in the contrib/polyml directory, which
+# is referred to as ML_HOME in the Isabelle Pure/General/sha1_polyml.ML source file.
+# ML_HOME is /usr/bin on Gentoo, and we want isabelle to depend o sha1-polyml.
+# For these reasons isabelle is patched to load it from
+# /usr/$(get_libdir)/sha1-polyml/libsha1.so
