我正在尝试安装http://www.ucm.es/info/Astrof/software/rmodel/rmodel.html中描述的 FORTRAN 程序 rmodel
./configure 失败并出现以下错误：

我尝试使用 ./configure 指向库export CPPFLAGS=-I/opt/X11/include，export CPPFLAGS=-I/opt/X11/include LDFLAGS=-L/opt/X11/lib但无济于事。（来自 Mountain Lion X11 库的这些建议不能 ./configure和Mountain Lion rvm install 1.8.7 x11 错误）
任何建议将不胜感激。
