Yes, so your freetype setup is broken as the message says. Any reason why your'e trying to compile this from sources when the binary is available from CRAN? I would suggest you use the binary unless you really know what you're doing (obviously you can replicate the CRAN setup but apparently you chose not to).

Cheers,
Simon
