[Swift-devel] coaster wget dependency

[Ben Clifford]

in the excitement of a new OS install, I have discovered that coaster has 
a wget dependency somewhere on the service side. that is common but not 
always installed everywhere (especially in places that prefer curl...).

the swift+coaster docs (if/when they appear) should probably document 
additional dependencies like this (and like GNU md5sum) that are 
potentially not installed places.
