Compilation notes:
	Downloaded source package R-3.1.0.tar.gz
	Local installation: /home/sgi/R310/
	On /apps/:
		$ ./configure --with-readline=no --with-x=no --prefix=/apps/R/
		$ make
		$ make check
		# $ make check-devel
		# $ make check-all
	Packages were downloaded from CRAN and installed with
		$ R CMD INSTALL <package_name.tar.gz>

Errors during compilation:
	GSL & DIVERSITREE
	Error installing diversitree: "configure: error: gsl-config not found, is GSL installed?".
	GSL installed from source to correct the dependencies.
	* Install GSL at /apps/:
		$ ./configure --prefix=/apps/GSL/
		$ make
		$ make check > log 2>&1
		$ make install
		$ make clean
	* Work around GSL erros:
		(1) Copy gsl-config from /apps/GSL/bin/ to /usr/local/bin
		(2) Modified the divertitree configure file to ignore version check:export 
			In line 3306, replace 'if test "${gsl_version_ok}" = no; then' for 'if test "${gsl_version_ok}" = yes; then
		(3) Remake divertitree tarball with tar -zcvf diversitree_0.9-7.tar.gz diversitree
		(4) sudo PATH=$PATH:`which gsl-config` LD_LIBRARY_PATH=$LD_LIBRARY_PATH:./apps/GSL/include/gsl/:/apps/GSL/lib/ /apps/R/bin/R CMD INSTALL diversitree_0.9-7.tar.gz 
	Example executiuon of R scripts calling for GSL libraries:
		LD_LIBRARY_PATH=$LD_LIBRARY_PATH:./apps/GSL/include/gsl/:/apps/GSL/lib/ /apps/Rscript BDiversitree1_v3.r tree0214 diet_birds.txt musse --t 1 --i 2000000 --s 1000
