[R-SIG-Mac] Macports installation problem

[美彦 馬場]

I do not want to mess this ML with yet another option, but Fink, another package manager for macOS, is also an option.  The main reasons I use Fink is to make sure GIS related CRAN packages (e.g. regal) are linked to Fink installed GIS packages (e.g. gdal).

Fink:
1. allows you to have multiple versions of R (e.g. 3.4, 3.3 and 3.2);
2.　has a number of CRAN/BioC packages to be stored in /sw/lib/R/3.4/site-library, /sw/lib/R/3.3/site-library and /sw/lib/R/3.2/site-library respectively
(CRAN/BioC libraries are linked to Fink packages);
3. allows users to use CRAN (saved in user directory) and Fink installed package; and
4. does not depend on non-System/Fink installed shared libraries  (so that regal will not be wrongly linked to user-installed gdal)

$ otool -L /sw/lib/R/3.3/site-library/rgdal/libs/rgdal.dylib 
/sw/lib/R/3.3/site-library/rgdal/libs/rgdal.dylib:
	/sw/lib/R/3.3/site-library/rgdal/libs/rgdal.dylib (compatibility version 0.0.0, current version 0.0.0)

> 1)  Use CRAN R, install dependencies needed for extended R capability on the OS as needed, from whatever source you prefer, or whichever is easiest for R to use
> 2)  If one chooses to install R using MacPorts or homebrew, be prepared to exercise a greater depth of computer science smarts
> 3)  Feel free to install other useful stuff using MacPorts or homebrew, whichever one prefers; there is unlikely to be any conflict with R
