[R-SIG-Mac] Installing the "jpeg" package?

[Spencer Graves]

Hello, All:


       How can I get the dev files for libjpeg installed under macOS 
10.15.1 Catalina?


       Simon Urbanek, the maintainer for the "jpeg" package, said I need 
them to install the "jpeg" package from sources.  I'm unable to get that 
package to install either as a binary or from sources;  see below.


       Suggestions?
       Thanks,
       Spencer Graves

/Library/Frameworks/R.framework/Versions/3.6/Resources/library

   There is a binary version available but the
   source version is later:
      binary  source needs_compilation
jpeg  0.1-8 0.1-8.1              TRUE

Do you want to install from sources the package which needs compilation?
