Hi,

During a rebuild of all packages in sid, your package failed to build on
amd64.

Relevant part (hopefully):
> make[2]: Entering directory `/«BUILDDIR»/twitter-bootstrap-2.0.2+dfsg'
> rm -rf bootstrap
> mkdir -p bootstrap/img
> mkdir -p bootstrap/css
> mkdir -p bootstrap/js
> cp img/* bootstrap/img/
> lessc ./less/bootstrap.less > bootstrap/css/bootstrap.css
> ParseError: Unrecognised input in /«BUILDDIR»/twitter-bootstrap-2.0.2+dfsg/less/mixins.less on line 522, column 7:
> 521     .spanX (@index) when (@index > 0) {
> 522       (~".span@{index}") { .span(@index); }
> 523       .spanX(@index - 1);
> 
> make[2]: *** [bootstrap] Error 1

About the archive rebuild: The rebuild was done on EC2 VM instances from
Amazon Web Services, using a clean, minimal and up-to-date chroot. Every
failed build was retried once to eliminate random failures.
