# sci-mathematics/isabelle requires sci-mathematics/sha1-polyml, to avoid
# this warning:
# ### 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
