You already have a version of $bm4 installed in $system_macrodir.
This isn't going to work, because aclocal is too stupid to use
an ordered search path. I'm therefore going to ignore the
one in this tree, and rely on the installed one. If this
results in errors, you will have deinstall the library that 
$bm4 is associated with.

If you don't like this policy, I suggest that you write to the
authors of aclocal and suggest that they improve their
program.
