impute dependency and gfortran error

Following the currently suggested work-around for the error that is thrown upon attempting to install the impute package due to no detectable gfortran did not lead me to resolution.

However, I could install ADAGEpath if I individually installed the impute package beforehand

install.packages("impute")

and then, when installing ADAGEpath (using either devtools or bioc) I dot not update the impute package when prompted.

I'm not sure how universal this work-around is but maybe ADAGEpath installation instructions could suggest it as a troubleshooting option?
