File::Tail needs to be built, yes, but there's no compile involved.

Time::HiRes is included with perl5.8.0 and up. If you are on an older perl, you can try just commenting out the use Time::HiRes line in File::Tail. Then it will use the normal time() and sleep() functions that don't have subsecond granularity.

I'm not sure what you are proposing to do other than time waiting...File::Tail tries to pick a reasonable wait period, and you can specify a maximum interval. You can even specify a maxinterval of "0 but true" if you really don't want to wait, but that sounds like a bad idea to me. (Haven't actually tried it, but looking at the code, I think it will work.)
