Unfortunately this package uses a hand rolled set of build scripts.
The maintainers are happy to add fixes to any problems but are not
keen on moving over to autotools. I don't get the impression many
people cross compile this one! That is a shame because it is very
useful with wireless sensor nodes.

There are a few nasty tests in the configure script that may well
cause problems in cross compiles when the host is not also linux based.

I will work on getting these fixed at source, but it may take a while
hence submission of this recipe in the meantime.

The reason this is the git version is recent patches to ensure
that the LDPATH variable was not ignored in linking.

This recipe includes some convenient scripts and blank config
files needed to get it up and running easily.
