Mono will using Gamin or FAM by default if it exists in the runtime. If either
doesn't exist then it will use KeventWatcher.cs. Add auto-check on Gamin and
FAM for dependency. Bump the PORTREVISION to have the fix of kqueue.
Rationale:
- KeventWatcher.cs is naive, it does not report changes made to
files within a monitored directory [1]
- KeventWatcher.cs is implemented in C#, it is therefore slower than
Gamin or FAM, which are implemented in C and C++, respectively
[1] this is a bug which should be reported to the vendor
Testing, using the attached WatchTest.cs:
With KeventWatcher.cs:
$ mono WatchTest.exe /somedir &
[1] 89857
$ touch /somedir/foo
OnCreatedEvent /somedir/foo
$ echo foo >> /somedir/foo
<nothing happens>
With Gamin:
$ mono WatchTest.exe /somedir &
[1] 89889
$ touch /somedir/foo
OnCreatedEvent /somedir/foo
$ echo foo >> /somedir/foo
OnChangedEvent /somedir/foo
