[gentoo-user] strange ebuild problem

[Helmut Jarausch]

Hi,
I have an ebuild containing

inherit git-r3

and

src_compile() {

	./build_all.sh
}

The script build_all.sh contains

[ -d csources ] || git clone --depth 1  
https://github.com/nim-lang/csources.git


When I try to build I get the strange error
fatal: unable to access 'https://github.com/nim-lang/csources.git/':  
Could not resolve host: github.com

But when I exec
git clone --depth 1 https://github.com/nim-lang/csources.git
in an xterm (i.e. without using 'ebuild') it succeeds.

What's going on here?

Many thanks for a hint,
Helmut
