[R-SIG-Mac] Failing to build R-devel: lzma.h missing

[peter dalgaard]

I have

$ cat ~/r-devel/BUILD/config.site 
CPPFLAGS=-I/opt/R/x86_64/include
LDFLAGS=-L/opt/R/x86_64/lib
with_tcl_config=/opt/R/x86_64/lib/tclConfig.sh
with_tk_config=/opt/R/x86_64/lib/tkConfig.sh

(even though Simon says I shouldn't use config files...)

I.e. you may need to set the *FLAGS in your setup (switch out the arch of course).
