cannot remove prior installation of package 'curl'

My builds are failing with the following error:

package 'curl' successfully unpacked and MD5 sums checked

Can you please try turning off the cache? Installation of binary packages is very fast.

Thanks for the suggestion.

This is what I should specify in yaml, right?

Alternatively, setting R_REMOTES_STANDALONE=true should help, see #135
