[R-SIG-Mac] Warnings installing from source

[Simon Urbanek]

Göran,

you can ignore the Fortran warnings, the ones you listed are not related to the code.

As for "undefined dynamic_lookup may not work with chained fixups" the easiest is to run
export MACOSX_DEPLOYMENT_TARGET=11.0
before you compile your package. Alternatively you can add -Wl,-no_fixup_chains to LDFLAGS.

Cheers,
Simon
