I found this file at /usr/lib/gcc/x86_64-amazon-linux/6.4.1/libgomp.spec. Copied this file to /usr/lib64/R/lib and /usr/local/lib64. Also provided sudo chmod 777 to both locations. Restarted rstudio-server and r session. Still getting the same error.

Adding the following symbolic links worked.

ln -s /usr/lib/gcc/x86_64-amazon-linux/6.4.1/libgomp.spec /usr/lib64/libgomp.spec
ln -s /usr/lib/gcc/x86_64-amazon-linux/6.4.1/libgomp.a /usr/lib64/libgomp.a
ln -s /usr/lib64/libgomp.so.1.0.0 /usr/lib64/libgomp.so
