+Getting scmutils/mit-scheme rolling on amd64 Linux (Debian-based)
+========================================================================
+
+(you'll have to do a lot of this as root or sudo along)
+
+First download and install regular 32bit binaries for your debian-like system.
+
+For mit-scheme, the generic linux binaries are for debian 3.1 and have some
+crusty library dependancies, but the .deb files won't install by default. You
+can either make them install or unpack the .debs and install by hand
+(sidestepping regular package management, kind of a faux pas, meh):
+
+    $ ar -x mit-scheme_7.7.90+20060906-3_i386.deb
+    $ tar xvf control.tar.gz
+    $ cp -a usr/* /usr/
+
+For scmutils just follow the directions for unpacking the .tar.gz.
+
+Then try to run the binary:
+
+    $ /usr/bin/mit-scheme
+
+or:
+
+    $ /usr/local/bin/mechanics
+
+Uh oh, missing file or some such message? Got some bad 32bit library mojo!
+Luckily we can install regular 32bit libraries in parallel. First,
+
+    $ apt-get install ia32-libs
+
+The binary still won't work, we're missing some libraries, so double check:
+
+    $ ldd mit-scheme-native 
+            linux-gate.so.1 =>  (0xffffe000)
+            libgdbm.so.3 => not found
+            libmhash.so.2 => not found
+            libcrypto.so.0.9.8 => not found
+            libncurses.so.5 => /lib32/libncurses.so.5 (0xf7f9c000)
+            libm.so.6 => /lib32/libm.so.6 (0xf7f78000)
+            libX11.so.6 => /usr/lib32/libX11.so.6 (0xf7e8c000)
+            libc.so.6 => /lib32/libc.so.6 (0xf7d61000)
+            /lib/ld-linux.so.2 (0xf7fe6000)
+            libXau.so.6 => /usr/lib32/libXau.so.6 (0xf7d5e000)
+            libXdmcp.so.6 => /usr/lib32/libXdmcp.so.6 (0xf7d58000)
+            libdl.so.2 => /lib32/libdl.so.2 (0xf7d54000)
+
+Installing regular versions didn't help, need to go get the 32 bit versions and
+install manually:
+
+    $ wget http://debian.lcs.mit.edu/debian/pool/main/o/openssl/libcrypto0.9.8-udeb_0.9.8c-4etch3_i386.udeb
+    $ wget http://debian.lcs.mit.edu/debian/pool/main/g/gdbm/libgdbm3_1.8.3-3_i386.deb
+    $ wget http://debian.lcs.mit.edu/debian/pool/main/m/mhash/libmhash2_0.9.7-1_i386.deb
+    $ dpkg -X libmhash2_0.9.7-1_i386.deb /emul/ia32-linux/
+    $ dpkg -X libgdbm3_1.8.3-3_i386.deb /emul/ia32-linux/
+    $ dpkg -X libcrypto0.9.8-udeb_0.9.8c-4etch3_i386.udeb /emul/ia32-linux/
+    $ ldconfig
