Hi Guix, The package libtgvoip (introduced with commit 494135d) fails to build on i686-linux [0]. Since this appears to be related to SSE2 these two Debian patches [1] [2], which disable SSE2 on i386 (the first patch does something unrelated, but it's required for the second one to apply), should fix it.
