Configuring automake to install to a path containing a '@' character breaks the compilation as shown in the attached typescripts. We found that we were able to work around the bug with the following patch:

diff --git a/bin/aclocal.in b/bin/aclocal.in
index 349f24a2..c8ab8b3e 100644
--- a/bin/aclocal.in
+++ b/bin/aclocal.in
@@ -69,7 +69,7 @@ $perl_threads = 0;
# ACLOCAL_PATH environment variable, and reset with the '--system-acdir'
# option.
my @user_includes = ();
-my @automake_includes = ("@datadir@/aclocal-$APIVERSION");
+my @automake_includes = ('@datadir@/aclocal-' . $APIVERSION);
my @system_includes = ('@datadir@/aclocal');

# Whether we should copy M4 file in $user_includes[0].

In considering alternative fixes we found that we could equally address the problem by replacing the double-quoted string with '@datadir@/aclocal-@APIVERSION@', similar to the use of @APIVERSION@ on line 30, but elected to continue the use of $APIVERSION in the event that there was a specific reason for using the Perl variable in this instance.
