Файл R Makevars не корректно переопределяет g ++

Я пытаюсь установить пакет R ‘lubridate’ на Centos 6. Поскольку lubridate требует более свежую версию g ++, чем стандартный компилятор на Centos 6, я скачал и скомпилировал версию gcc 4.9 (из того, что я читал, lubridate требует > v4.8)

Затем я добавил строки:

CXX=/opt/gcc_4.9.1/rtf/bin/g++
CC=/opt/gcc_4.9.1/rtf/bin/gcc -std=gnu99

в файл ~ / .R / Makevars, чтобы попытаться заставить его использовать более новый компилятор, но когда я пытаюсь установить lubridate, я получаю эту ошибку:

Что интересно, похоже, что он пытается правильно использовать правильный gcc:

/opt/gcc_4.9.1/rtf/bin/gcc -std=gnu99 -I/opt/R/R-3.3.3/include -DNDEBUG -I. -I./cctz/include/ -I./cctz/src/ -I/usr/local/include -I"/opt/R/R-3.3.3/library/Rcpp/include"  -O3 -Wall -pipe -pedantic -std=gnu99 -fopenmp -fpic  -O3 -Wall -pipe -pedantic -std=gnu99 -fopenmp -c datetime.c -o datetime.o

но не правильный g ++ (не перечисляя полный путь, который я определил в файле ~ / .R / Makevars):

g++ -std=c++0x -I/opt/R/R-3.3.3/include -DNDEBUG -I. -I./cctz/include/ -I./cctz/src/ -I/usr/local/include -I"/opt/R/R-3.3.3/library/Rcpp/include"   -fpic  -g -O2 -c RcppExports.cpp -o RcppExports.o

Если я изменю строки в файле ~ / .R / Makevars на следующие:

CXX=g++
CC=gcc

Тогда похоже, что оба исполняемых файла становятся обычными системными:

g++ -std=c++0x -I/opt/R/R-3.3.3/include -DNDEBUG -I. -I./cctz/include/ -I./cctz/src/ -I/usr/local/include -I"/opt/R/R-3.3.3/library/Rcpp/include"   -fpic  -g -O2 -c RcppExports.cpp -o RcppExports.o
gcc -I/opt/R/R-3.3.3/include -DNDEBUG -I. -I./cctz/include/ -I./cctz/src/ -I/usr/local/include -I"/opt/R/R-3.3.3/library/Rcpp/include"  -O3 -Wall -pipe -pedantic -std=gnu99 -fopenmp -fpic  -O3 -Wall -pipe -pedantic -std=gnu99 -fopenmp -c datetime.c -o datetime.o

Есть ли другой файл, который имеет приоритет над моим определенным местоположением g ++ в файле ~ / .R / Makevars? Реальный вопрос в том, как заставить R использовать /opt/gcc_4.9.1/rtf/bin/g++ здесь?
