R: libR.pc doesn't include path to all includes

[nstanger (Nigel Stanger)]

graphviz @2.26.3_1+java+macosx+perl+php+python26+r+rsvg+tcl to be precise ☺, but it’s +r that it fails on. It fails during the build phase trying to find Rconfig.h (log attached):

:info:build In file included from /opt/local/lib/R/include/Rdefines.h:26,
:info:build                  from gv_R.cpp:743:
:info:build /opt/local/lib/R/include/R_ext/RS.h:27:54: error: Rconfig.h: No such file or directory

It looks like the R includes are not being set up correctly. Out of the box it sets R_CFLAGS to “-I/opt/local/lib/R/include”, but Rconfig.h is in /opt/local/lib/R/include/x86_64. I manually ./configured with R_CFLAGS set to “-I/opt/local/lib/R/include -I/opt/local/lib/R/include/x86_64” and it appears to build correctly.

Yes, R seems to have moved where it puts its headers; now everything that uses R is broken. Hooray for R. R's libR.pc pkgconfig file makes no mention of this extra directory. Sounds like an R bug.

The pkg-config information was overlooked when R switched to architecture-dependant subdirectories. I've told the developers so this should be fixed in an upcoming release. In the meantime I've modified the R port so that the path to Rconfig.h is also included in the pkg-config info.

Thank you, fixed in r72437.
