As of the current writing, Gwydion Dylan supports several flavors of Unix-like systems, including GNU/Linux (on x86 and PowerPC machines), FreeBSD, and Solaris. Other systems are supported but not current, including Windows NT and several varieties of Unix. Binary packages are available for a wide range of Linux distributions. Bringing an ignored port up to date requires one or more recompilations. Creating a new port requires several days to a few weeks of work, and a familiarity with both Dylan and the target system.
