我在ubuntu9.04下编译一个fortran程序，这个程序是网上下载的，它的makefile默认的编译器是g77，同时还提供了其他的编译选择，我先用默认的编译，出错了，然后我将FC改为ifort，还是不行,哪位大侠告诉我该怎么办啊？

另外，我希望这个程序运行时能给出每一步迭代所花的时间，这个貌似也要改makefile，可我不知道怎么改

下面是我的makefile部分内容，拜托好心人帮我看看，先谢谢了

楼上的大侠，我刚才发的那个makefile是一个较低版本的，现在我才发现那个软件又出了个新的版本，这个软件是用fortran90编写的，它的makefile是这样的：

我把FC用g95，gfortran，g95，ifort都试过了，但是都出错，比如我用g95时，出现如下：

cpp -P -traditional-cpp -Ddp ddprecision.f90 \
ddprecision_cpp.f90
g95 -c -O2 ddprecision_cpp.f90 -o ddprecision.o
make: g95: Command not found
make: *** [ddprecision.mod] Error 127

拜托大侠耐心点帮我看看，我都快急死了
