make install (Linux Mint Mate 32bits / Go 1.0.2) gives as a result:
cd pango && go install -x
go install: no install location for _/home/arie/go-gtk/pango
make: *** [install] Error 1
same error here using ubuntu 12.04 and the go version from that distro
I can't reproduce it.
This is caused by code not being in $GOPATH. Use the go get method to avoid it.
Same problem for me on Linux (Aptosid, a Debian derivative).
I get this error when I don't keep the source code in a src directory under $GOPATH
Note that the directory must be called src and it must be directly under the directory pointed to by $GOPATH
