What version of libuduits2 do you have installed on your system. I seem to recall seeing this if one has an older version of the library (< 2.2?).

[wittenberg]

Currently, I have libudunits2-0 (version 2.2.25-2) installed.

[edzer]

The link step is wrong: -ludunits2 -lexpat is missing. I see:

Could you maybe unpack the library, and then install with

R CMD INSTALL udunits2

and then verify the contents of udunits2/src/Makevars? It should have the -ludunits2 -lexpat in it.

I just tested this. {udunits2} has no plain Makevars and adding it with the same contents that are in Makevars from {units} does not help.
