Hi list,
I have encountered the "Cannot find xml2-config" problem too during XML package installation on my 64-bit Redhat (v. 6.4) linux machine. After looking through the old posts I checked all the necessary libraries and they all seem to be properly installed (see below). I don't understand why R can't see the xml2-confg during the installation process. Help, please!
Many thanks!
Tao
