[Bug-mcron] ‘mcron’ doesn’t have its own modules in its search path

[Ludovic Courtès]

Hi again,

By default the ‘mcron’ command doesn’t have its own modules in its
GUILE_LOAD_PATH and thus fails to start because it cannot find (mcron
scripts mcron).

I think the problem is that the PACKAGE_LOAD_PATH and
PACKAGE_LOAD_COMPILED_PATH cpp macros are given the wrong value.  They
should be equal to $(guilesitedir) and $(guilesitegodir).
