For ecraven specifically, the astrolog package needs its astrolog.dat file packaged with it since the astrolog.dat file controls the operation of astrolog itself. I was able to fix that deficit after having downloaded and installed the aur package as a result of prior use of the software. That file belongs in /usr/share/astrolog and the DEFAULT path in astrolog.h needs to point to /usr/share/astrolog as well before compilation. The file ephemall.zip also ought to be extracted into /usr/share/astrolog because that file on the same site as the astrolog software is the ephemeris files for astrolog. The accuracy of calculations improve with use of ephemeris files and Lilith can then also be calculated. Other than that, this is a good package and builds well.
