Not installing to hard-coded locations vs polkit's fixed location

[Mike Fleetwood]

Hi,

I'm working on adding installation of a polkit action file into
GParted's build and install system, however the polkit daemon only
recongises action files installed into the single location of
/usr/share/polkit-1/action/.

Currently the Makefile.am contains this line:
(larger fragment of the Makefile.am below)
    polkit_actiondir = $(datadir)/polkit-1/actions

This allows 'make distcheck' to work and when GParted is built with
'./configure --prefix=/usr' for the polkit action file to be installed
into the required location.  However when prefix is left defaulted to
/usr/local the polkit action file is obviously installed into
/usr/local/share/polkit-1/action/ which is ignored by the polkit daemon.

Are there any resolutions to this?
I could:
1) Leave things as they are and document it as the builders
   responsibility, that when prefix defaults to /usr/local, or anything
   other than /usr, that the polkit action file will need manually
   installing into the correct location under a unique name so as not to
   overright any distro package provided copy.
2) Set polkit_actiondir to /usr/share/polkit-1/action but that is
   against automake guidance and breaks 'make distcheck'.
Are there any other solutions which are reasonable?

Thanks,
Mike
