I've been trying installing R package igraph but during installation I keep receiving the following error:
** libs
gfortran -fno-optimize-sibling-calls -fpic -g -O2 -c AMD/Source/amd.f -o AMD/Source/amd.o
make: gfortran: No such file or directory
make: *** [/usr/lib64/R/etc/Makeconf:191: AMD/Source/amd.o] Error 127
I've tried both installing from CRAN and from github repository with the same result. It seems that during installation there is an error on level of compiling C igraph library. I've also tried pre-compiling it but it doesn't work. File AMD/Source/amd.f is present in igraph repository.
Here is my sessionInfo:

I'd be grateful for any suggestion.
As @r2evans suggested in his comment, the answer is simple: I needed to install gfortran, I had misunderstood the error message... That's all folks!
