Bug#1029112: Surprise build issue with ibus-libzhuyin

[Gunnar Hjalmarsson <gunnarhj@debian.org>]

Package: src:ibus-libzhuyin
Version: 1.10.2-1
Severity: serious
Tags: ftbfs

Hello!

ibus-libzhuyin 1.10.2-1 failed to build. This is the relevant part of 
the buildlog:

Making all in model
make[4]: Entering directory '/<<PKGBUILDDIR>>/data/model'
wget http://downloads.sourceforge.net/libzhuyin/models/model13.text.tar.gz
/bin/bash: line 1: wget: command not found

And yes, it's true that wget is not included in Build-Depends. But 
previously that has not been needed. This is from the buildlog for the 
latest successful build:

Making all in model
make[4]: Entering directory '/<<PKGBUILDDIR>>/data/model'
rm -f phrase_index.bin pinyin_index.bin addon_phrase_index.bin 
addon_pinyin_index.bin bigram.db tsi.bin
gen_binary_files --table-dir ../../data/model
import_interpolation --table-dir ../../data/model < 
../../data/model/interpolation2.text
gen_unigram --table-dir ../../data/model

or just:

Making check in model
make[3]: Entering directory '/<<PKGBUILDDIR>>/data/model'
make[3]: Nothing to be done for 'check'.

I have not found any code changes which would explain the new behavior. 
And when trying (in an Ubuntu PPA) to add wget to Build-Depends, it 
failed to resolve the download URL. (It builds fine on my harddisk, though.)

I figured out that this patch would help it build successfully:

--- a/data/Makefile.am
+++ b/data/Makefile.am
@@ -27,7 +27,6 @@

  SUBDIRS = \
          icons \
-        model \
          $(NULL)

  appdatadir = @datadir@/appdata

But since I don't know how that would affect the functionality of the 
package, I have left it in its failed state for now.

In other words: I need help to solve this.
