我正在尝试安装deldirR 中的包通过install.packages("deldir",type = 'source')但收到以下错误消息（这是 OSX Mavericks）：
* installing *source* package ‘deldir’ ...
** package ‘deldir’ successfully unpacked and MD5 sums checked
** libs
gfortran-4.8 -fPIC -g -O2 -c acchk.f -o acchk.o
make: gfortran-4.8: No such file or directory
make: *** [acchk.o] Error 1
ERROR: compilation failed for package ‘deldir’
gfortran 4.8 似乎在我的系统上可用，但是：
> gfortran -v
Using built-in specs.
COLLECT_GCC=gfortran
COLLECT_LTO_WRAPPER=/usr/local/gfortran/libexec/gcc/x86_64-apple-darwin13/4.8.2/lto-wrapper

Thread model: posix
gcc version 4.8.2 (GCC)
将 gfortran-4.8 符号链接到 gfortran 之后，我得到了一些进一步的结果，但仍然失败了：
