[Click] unknown element class

[Enrico]

Hi,
I'm a inexpert click and linux user and I've some problems.
I had compiled click (userlevel) and i write a configuration to
run...but when I run it the response displayed is (for example) 
"unknown element class 'TimeRange'".
In the clickfolder/elements/analysis there are timerange.cc and
timerange.hh ... but in clickfolder/userlevel there are not timerange.d
and timerange.o.
Help me please!

p.s. sorry... my english is horrible..
