There is one error with a fairly clear error message:

 > Error in firstlib(which.lib.loc, package) :
 >    Tcl/Tk support is not available on this system

and one warning:

 > Found the following sources/headers with CR or CRLF line endings:

What do you find unclear about the messages?  You don't have Tcl/Tk 
support, but something you are doing requires it; you have used ASCII 
standard text files (as on Windows) or possibly the weird files that 
used to be used on MacOS, rather than following the Unix conventions 
that some systems need.
