2.2 MacOS X binary distributions

MacOS users can either compile the UNIX source code (see Compiling from UNIX source) or install the contributed Asymptote binary available at

http://www.hmug.org/pub/MacOS_X/BSD/Applications/Publishing/asymptote/

However, instead of trying to install from these preconfigured binary distributions, which ave strict architecture and library dependencies that many installations do not satisfy, we recommend installing Asymptote directly from the official source:

Note that many MacOS X (and FreeBSD) systems inexplicably ship with an extremely old GNU readline version (4.1, dated 21 March 2000); for full interactive functionality, a readline version of at least 4.2 or later (16 April 2001) is required.
