===> Building for libsecret-0.18.6
  GEN      temp-dbus-generated.c

sed: -e expression #1, char 2: unknown command: `1'
Makefile:2650: recipe for target 'secret-dbus-generated.c' failed
gmake: *** [secret-dbus-generated.c] Error 1


From the error message it appears that this is base sed - GNU sed
compatibility issue as most upstream builds use GNU utitlies.

Came across this while building www/vimb. Request advice.
