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

[Duncan Murdoch]

I'm trying to build R-devel.  I used this command line to configure it:

../R-devel-src//configure -C --enable-R-shlib --enable-memory-profiling 
--x-includes=/opt/X11/include --x-libraries=/opt/X11/lib 
--with-tcl-config=/opt/R/arm64/lib/tclConfig.sh 
--with-tk-config=/opt/R/arm64/lib/tkConfig.sh 
PKG_CONFIG_PATH=/opt/R/arm64/lib/pkgconfig:/usr/lib/pkgconfig

(I found that in the old config.log, with "pkg-config" in the 
PKG_CONFIG_PATH instead of "pkgconfig".  Neither one works.  I think it 
also matches the suggestion in the R-admin manual.)  Is there something 
missing?  It fails with this error at the end:


   checking for lzma_version_number in -llzma... yes
   checking for lzma.h... no
   configure: error: "liblzma library and headers are required"

But I see lzma.h in /opt/R/arm64/include, and that's where pkg-config 
--cflags liblzma says it should be.  I tried removing PKG_CONFIG_PATH 
and got the same result.
