xtrans-dev 1.3.5-1 (armhf binary) in ubuntu wily

 xtrans includes a number of routines to make X implementations
 transport-independent; at time of writing, it includes support for UNIX
 sockets, IPv4, IPv6, and DECnet.
 .
 xtrans is not actually a library in itself; it includes .c files which are
 then used in the compilation of X servers, libraries, et al.
