Re: mathgl: missing-dependency-on-libc needed

[Dimitrios Eftaxiopoulos <eftaxi12@otenet.gr>]

Hello Anton,
Thanks for looking at it. I have built the package with pbuilder under 
distribution experimental and architecture amd64. Other combinations (unstable 
+ amd64, experimental + i386 etc.) will probably fail due to symbols 
mismatches. 

I use the commands

$sudo pbuilder --create --basetgz /var/cache/pbuilder/base-experimental-
amd64.tgz --distribution experimental --architecture amd64

$sudo pbuilder --update --basetgz /var/cache/pbuilder/base-experimental-
amd64.tgz --distribution experimental --architecture amd64 --override-config

for creating and updating the clean chroot environment. Then I use 

$BUILDER=pbuilder git buildpackage --git-pbuilder --git-dist=experimental --
git-arch=amd64 --git-debian-branch=experimental

for building.

The package can be found at 

http://anonscm.debian.org/gitweb/?p=debian-
science/packages/mathgl.git;a=shortlog;h=refs/heads/experimental

Best regards
Dimitris
