[R-SIG-Mac] Missing qpdf

[Simon Urbanek]

Matt,

First option: try using the latest R from https://mac.R-project.org since the latest releases include qpdf in the distribution so there is no need to install it externally.

Second option: use R instead of RStudio since the latter is just a complicated way to call "R CMD check" so calling it directly should work.

Third option: ask RStudio support how to get it to work since that requires manipulation of (exported) PATH inside RStudio.

Cheers,
Simon
