I tried to import the ServoVarSpeed library and keep getting this error in my Mac.

core.a(main.cpp.o): In function main': /Users/Derrick/Downloads/ undefined reference to setup'
/Users/Derrick/Downloads/ undefined reference to `loop'

I know less than zero about libraries, - Please advise how to proceed,

Thank you

Posting your code would be a good start.

A wild guess.

Your program does not have setup() or loop() functions, but let's see it.

Looks like you are trying to 'Verify' or 'Upload' the library as if it were a sketch. Put the library in the "libraries" sub-folder of your sketch folder in a folder named after the .h file (so probably libraries/ServoVarSpeed/).
