Re: CS installation on Mac os x

This doesn't really appear to be a problem with the 3rd-party
dependences since it is stating that main() can not be found. What is
the actual build command which fails? Is it building an application at
this point or a plugin? If it's a plugin, then it may be the case that
when CS is built with this particular compiler, the plugin needs a
main(), as is the case with Unix. See, for instance,
CS/include/csutil/unix/csosdef.h:CS_IMPLEMENT_PLATFORM_PLUGIN.
