[R-pkg-devel] Fixing travis build fail due to fftwtools fatal error (fftw3.h: No such file or directory)

[Marta Karaś]

Dear all,

I have been facing travis build fail on linux xenial due to *fftwtools
fatal error* (fftw3.h: No such file or directory) with my R package. The
error appeared at a random time a few months ago (at a random time := I do
not link it with any fftwtools-function related change commit I did) and
persists.

There is not much I achieved in googling and trying to decipher it, sadly;
I am hoping maybe some Community members saw a similar error with their dev
work and can suggest a hint/solution?
