[DRE-maint] Bug#1088785: ruby-msgpack: FTBFS on ppc64el: Automatic compaction isn't available on this platform

[Paul Gevers]

Source: ruby-msgpack
Version: 1.4.2-2
Severity: serious
Justification: ftbfs patch
Control: block 1082419 by -1

Hi,

Bug 1082419 is blocked by a FTBFS on ppc64el. The issue seems to be 
(judging from the error log) that auto_compact is used during testing, 
but that isn't implemented on ppc64el. My attached proposed fix is to 
*try* to do auto_compact, but don't fail if that fails (inspired by the 
several lines higher). I've tested that amd64 still builds. My test 
builds on ppc64el on debomatic-ppc64el.d.n seem to be blocked by issues 
with the infrastructure, so I have not tested my fix yet.

If you think my fix is good, please upload. If not, I'll probably NMU 
once I confirm it builds on debomatic.

Paul

+Subject: tests: avoid FTBFS on ppc64el by *trying* auto_compact
+
+The current version fails to build on ppc64el with the following error:
+`auto_compact=': Automatic compaction isn't available on this platform (NotImplementedError)
+
+So, to avoid failure, catch the exception.
