I'm trying to install biocLite(gcrma) and it appears to be hanging up on the Xvector & IRanges build.  Can anyone give me a clue about this matchSignature() error?

After correcting some of the out of date packages, I'm now stuck on Rgraphviz and RcppArmadillo.  Neither will build under RHEL6.8 because they want a GCC 4.6 compiler.  That seems a bit extreme.
