+Test the installation of toolchains package by building and installing
+a mock compiler package using dune's toolchain mechanism.

+  $ make_lockdir
+
+We create a fake compiler by creating a configure file.
+
+  $ mkdir fake-compiler
+  $ cat > fake-compiler/configure << 'EOF'
+  > #!/bin/sh
+  > PREFIX=$1
+  > echo $PREFIX > prefix.txt
+  > EOF
+  $ chmod a+x fake-compiler/configure
+
+We add a shell script to be installed as a fake compiler
+
+  $ mkdir -p fake-compiler/target/share/bin
+  $ cat > fake-compiler/target/share/bin/ocamlc << EOF
+  > #!/bin/sh
+  > echo "Hello from fake ocamlc!"
+  > EOF
+  $ chmod a+x fake-compiler/target/share/bin/ocamlc
+
+We make sure the installed script is installing the script at the correct
+location
+
+  $ cat > fake-compiler/make << 'EOF'
+  > #!/bin/sh
+  > prefix=$(cat prefix.txt)
+  > target=${DESTDIR}${prefix}
+  > install() {
+  >   mkdir -p "${target}"
+  >   cp -r target/* "${target}"
+  > }
+  > install
+  > EOF
+  $ chmod +x fake-compiler/make

+We generate the lockfile for the fake compiler
+
+  $ cat > dune.lock/ocaml-base-compiler.pkg << EOF
+  > (version 1)
+  > (build
+  >  (run ./configure %{prefix}))
+  > (install
+  >  (run ./make install))
+  > (source
+  >  (copy $PWD/fake-compiler))
+  > EOF
+
+We generate the lock file for the package to demonstrate the variable is
+replaced with the path to the sandbox inside of the path to the non-relocatable
+location.

+  > (version 1)
+  > (build
+  >  (run sh -exc "echo %{pkg:ocaml-base-compiler:share}"))

+We try to build the dependency to show that it echoes the wong path. Until we
