Hi there,

I am able to build and install MonetDB v11.21.19 "Jul2015-SP4" by following and example from https://www.monetdb.org/wiki/MonetDB:Building_from_sources

But when I try build MonetDB v11.27.5 on same machine I get this error (for a full log info see https://drive.google.com/drive/folders/0B7dMycp0Ku-NTlRsZW95R0xCNmM?usp=sharing):
