[igraph] makefile errors in the (develop branch) interfaces/R folder

[Glenn Lawyer]

Hi,

Trying to build the develop branch; I've managed to get the source downloaded and built, but the makefile in "interfaces/R" fails.

Do I need to run a command before I run make in this directory?

Here is what I do (running a recent Debian machine):
$ git clone https://github.com/igraph/igraph.git -b develop
$ cd igraph
$ ./bootstrap.sh
$ configure
$ make
$ make check (everything is ok)

$ cd interfaces/R
$ make
(lots of mkdir -p, and then:)
printf "%s" "OBJECTS=" >> igraph/src/Makevars.in
cat object_files >> igraph/src/Makevars.in
cd igraph; autoheader; autoconf
