yeah, r-base is hitting this bug. As a _workaround_, you can patch the
r-base package with the joined patch. It'll disable the '-g' flag when
running the configure test. With that, the tcltk.so lib is generated
(and thus the tcl/tk deps are there too). Please note that I've not
tested if the R tcl/tk stuff is working, I've only checked that the lib
was built.
