Evening folks:

Running R 4.2.0 on Linux Mint 19.3. When I tried to update package
nloptr the operation failed with this error text seeming to be key to
the problem.

CMake Error: The source directory
"/tmp/RtmpCNCU3l/R.INSTALL21c510095118/nloptr/src/CMAKE_RANLIB=/usr/bin
/ranlib" does not exist.
Specify --help for usage, or press the help button on the CMake GUI.
Unknown argument -j
Unknown argument 2
Usage: cmake --build <dir> [options] [-- [native-options]]
Options:
  <dir>          = Project binary directory to be built.
  --target <tgt> = Build <tgt> instead of default targets.
                   May only be specified once.
  --config <cfg> = For multi-configuration tools, choose <cfg>.
  --clean-first  = Build target 'clean' first, then build.
                   (To clean only, use --target 'clean'.)
  --use-stderr   = Ignored.  Behavior is default in CMake >= 3.0.
  --             = Pass remaining options to the native tool.
CMake Error: The source directory
"/tmp/RtmpCNCU3l/R.INSTALL21c510095118/nloptr/src/nlopt" does not
exist.
Specify --help for usage, or press the help button on the CMake GUI.
cp: cannot stat 'nlopt/include/*': No such file or directory

Uninstalled the package and tried reinstalling. Same stumble so I now
no longer have it at all, and it's needed to load Rcmdr.

Any help sorting this out would be appreciated. Please... :-(
