Perple_X data files should be downloaded from the most recent archive (e.g., Perple_X_6.7.6_data_files.zip) at
The following link provides a statically linked 64 bit LINUX version of Perple_X (courtesy of Ondrej Lexa, Charles University, Prague) that is updated daily at 02:30 GMT+1 (do not use any data files included in this archive, see above)
If you are concerned that current version of the sources may not have compiled correctly refer to:
Ondrej's script automatically compiles the version of Perple_X marked by the "download" tag in Ondrej's Perple_X Bazaar VCS, unfortunately I have had some problems updating the "download" tag. To be certain that you are using the current version of Perple_X compare the source date printed to the user console when any Perple_X program is executed with the last update in www.perplex.ethz.ch/perplex_updates.html. If the binary sources are older than the last source update, then please contact me (james dot connolly at erdw dot ethz dot ch) and I will correct the problem.
