Comment(by sebastic):

 There is now LASzip packaging, see:
  * [https://bugs.debian.org/cgi-bin/750731 Debian Bug #750731 ITP: laszip
 -- Lossless LiDAR compression]
  * [http://anonscm.debian.org/cgit/pkg-grass/laszip.git git repository for
 the laszip package]

 Unfortunately the LASzip source uses a modified copy of the FastAC
 Readme], [http://www.cipr.rpi.edu/research/SPIHT/EW_Code/FastAC.zip
 Source]) algorithm whose license doesn't allow modification making it
 incompatible with the LGPL-2.1 license used by LASzip. See the thread
 started by the Debian FTP master feedback:

 devel/2014-August/021701.html Comments regarding

 I've contacted the FastAC authors asking them to consider relicensing the
 code, Amir Said replied that he would be glad to see it used in Free
 Software projects and asked what they needed to do. I've recommended using
 the [http://spdx.org/licenses/BSD-2-Clause BSD-2-Clause] license which is
 close to the currently license of FastAC and most widely compatible with
 other Free Software licenses.

 It has been very quiet ever since. I'll contact the libLAS & LASzip
 authors to restart the discussion around the troublesome FastAC code to
 hopefully get this issue resolved.
