But the better method would be to get the desired effect without string 
interpolation here, i.e. to write something that becomes

my @automake_includes =
('/ptmp/bavier/projects/spack/opt/unknown_arch/gcc@4.3.4/automake@1.14.1-56e69c6c/share/aclocal-' 
. $APIVERSION);

Please see the attached (passes make check on Debian x64, but otherwise 
untested) patch
