Bug#1073425: php-oscarotero-gettext: FTBFS: make[1]: *** [debian/rules:18: override_dh_auto_test] Error 1

[James Valleroy]

The build is working in testing, so this regression is due to a recent change. 
I've narrowed down the cause of the issue to a change in one of the following 
packages:
- libxml2:
  - build works with 2.9.14+dfsg-1.3+b3
  - build fails with 2.12.7+dfsg-3+b1
- libxml2-utils:
  - build works with 2.9.14+dfsg-1.3+b3
  - build fails with 2.12.7+dfsg-3+b1
- libxml-libxml-perl:
  - build works with 2.0207+dfsg+really+2.0134-1+b3
  - build fails with 2.0207+dfsg+really+2.0134-4
