Thanks.
well, i thought I can just sneak by all that stuff if I just compile on my host machine, and copy the binary over to the slug, where all the libraries and whatnot are 😉
edit:
in case anyone else gets a weird error about missing terminating ” character in version_info.h, its an error in the glibc Makefile.
It only really becomes apparent in recent Ubuntu installs, since some genious there swapped out the symlink /bin/sh from bash to dash.
And dash isnt compatible to that extent.
A quick fix is to revert the symlink back to bash. Might be trouble if you aint got root.
