Hi, I have some suprising problems trying to compile software for openwrt.

I am on Debian testing and my perl is 5.26.1.

When I try to compile the openwrt-toolchain it fails at one point because a perl-script gets generated that contains this: 

sub substitute_ac_subst_variables
{
  my ($text) = @_;
  $text =~ s/\${([^ \t=:+{}]+)}/substitute_ac_subst_variables_worker (
+$1)/ge;
  return $text;
}

Unfortunately my perl dies here with "Unescaped left brace in regex is illegal here in regex".

I decided to try an older perl and installed 5.20.3 but the problem persisted.

So I tried the even older perls 5.12.5 and 5.10.1 but to my surprise the attempt to install then via perlbrew failed in the tests.

So it seems the openwrt-toolchain cannot deal with the behaviour of newer perls while the installation of old perls fails...

Before I now set up a VM with an older debian-version, I wanted to see if anybody has any other idea on how to proceed.

Many thanks!
