Strange. On i686-linux it seems to require autotools http://hydra.nixos.org/build/29214063/nixlog/1/raw but x86_64-linux is fine.

@vcunat, that is quite strange. I played around with it and it seems related to the file timestamps. In particular if I do a touch aclocal.m4 configure Makefile.in in a nix-shell -a pdf2svg it builds just fine while it fails otherwise (on i686, for whatever reason it builds fine regardless on x86_64).

I created PR #11888 to fix the build. In the PR I simply added autoreconfHook as a dependency to force a regeneration of the autotool files.

By the way, thanks for the notice! I had indeed only tested this package on x86_64. I did not predict this interesting issue :-)
