What's the usual way that openldap does this for packages installed in 
non-standard locations e.g. if I want to have my own private build of 
cyrus-sasl?  Is it up to the user to specify 
CPPFLAGS=-I/path/to/nonstd/sasl/include and 
LDFLAGS=-L/path/to/nonstd/lib ?  Does openldap configure have a 
--with-sasl=/path/to/nonstd/sasl option?

Perhaps a better question is - how would you like it to work?  I'm 
assuming there must be some way specify which crypto you want to build 
openldap with - is that a configure option?

The original patch - 
ftp://ftp.openldap.org/incoming/openldap-2.4.11-nss-20080911.patch - 
assumes the use of pkg-config - I suppose that is not sufficient.
