@franzbischoff I am not sure now if I used the master branch last time, but I did now, and from 24c9ff2 commit I get the same failure.

[franzbischoff]

Unfortunately I had no spare time to fix that yet... sorry @barracuda156
Have you tried to install the built package from CRAN?

Pre-built option does not work for two reasons:
– it does not exist for PowerPC;
– for x86 and arm64 we need reproducible builds from source in MacPorts, so grabbing a binary is not really an option (it is done when absolutely required, like when a bootstrap compiler is needed to build itself).
