Typically, this comes up for the testing part of the package (make
check).  In the simplest case, set TESTS_ENVIRONMENT (used for the
programs listed in the TESTS macro).  Otherwise, you can use a wrapper
script (or scriptlet to be sourced) for your uninstalled programs that
sets an environment variable that overrides the compiled-in value of
DATADIR.  This approach has the advantage of not requiring a compile
when installing.

Hope that helps.
