Although I'm certain the ATLAS folks could do this, I don't quite see why
you care.  It only takes a couple of more lines in configure.in to check
for multiple ATLAS libraries as to check for one.  The patch I posted does
this.

How do you know what /some/dir is?  AC_CHECK_LIB doesn't give it to you.
Do you require the user to specify the directory to configure...possibly in
addition to a -L flag in LDFLAGS so that AC_CHECK_LIB works?  It seems much
easier just to link to -latlas.

Do you have some particular objection to the scheme I used in the patch I
posted?
