I found a solution here: https://support.rstudio.com/hc/communities/public/questions/201688563-Problem-with-Mac-Yosemite-Beta-and-RStudio-not-finding-TeX-distribution

It turns out that Adam Maxwell noted that Yosemite beta has a significant bug in passing environment variables to subprocesses.

After installing gfortran as in OS X package installation depends on gfortran-4.8 .

This works: create an alias in your .bash_profile

alias fixrs="launchctl setenv PATH /usr/texbin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/opt/X11/bin"

Then close and open the terminal.

And execute the fixrs command in the terminal before launching RStudio.

Then I could build igraph successfully.
