The lesstif2 package on which your package depends or build-depends is
destined to be removed from the archive before the release of Jessie.
More information can be found in the Debian wiki .
Please update your package to build against the motif package instead.
In most cases this can be done by simply replacing the build-depends on
lesstif2-dev with libmotif-dev, however please do verify proper
behaviour before uploading.
Your package appears to not depend on any other lesstif2-dependent
packages and its only dependent package is itself.
