Multiple warnings when installing package on CentOS

[JoFAM]

Hi,

I installed the Rttf2pt1 package on a CentOS server from CRAN, but got a very long list of warnings while doing so. Nothing that scared me, but too many to ignore imho. I installed the windows version on my desktop as well, and there everything went fine. Didn't check thoroughly, but it appears as if everything is working as intended.

The output shown in the R console after install is attached in a separate file
Rttf2pt1Install.txt

cat /proc/version output:
