R install.packages polyclip: where is config.log? No answer in prior posts

Question

Attempting to install R package ggforce encountered following error installing dependency polyclip which referred me to config.log. However, config.log is not found below ~/, /tmp, or /var/log I checked this via

find . | grep config[.]log 

Tried install.packages("ggforce",keep_outputs = TRUE) which did not provide any additional information;

 install.packages("ggforce",keep_outputs = TRUE,verbose = TRUE)

"configure: error: in `/tmp/RtmpAkq4Vm/R.INSTALL6c31457f19ba/polyclip'"

however /tmp/RtmpAkq4Vm did not exist post installation.

Can somebody tell me where it is?

Error detail:

Answer 1

Installing package polyclip choked on something in my .Rprofile. I moved it out of the way and the ggforce install completed successfully.

I got a link to the config.log file during installation before it presumably got deleted by sourcing the following in another bash shell:

while true ; do
    if [  -e config.log ]
        then return
    fi
    save=`find /tmp -name config.log -exec ln {} config.log \;` 
done 2>/dev/null

config.log contained the following after the error occurred:

This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.

It was created by polyclip configure 1.9-1, which was
generated by GNU Autoconf 2.69.  Invocation command line was
