[R-pkg-devel] qpdf problems on Windows 10

[Spencer Graves]

Hello, All:


	  "R CMD check Ecfun_0.2-4.tar.gz" ends, <<qpdf.exe" --version' had 
status 123 Error: invalid version specification 'NA'>> on Windows 10 
under R 4.0.3;  see below.


	  I think I have a defective install of qpdf, but I can't find 
information on how to fix it.  I tried to install it, because "Writing R 
Extensions" seemed to recommend it.  Now I have this problem.


	  Suggestions?
	  Thanks,
	  Spencer Graves
