liblua dependency missing, causing Perl Inline to fail

[Jari Turkia]

1) System info:
Description: Ubuntu 14.04.1 LTS
Release: 14.04

2) Package info:
lua-bitop:
  Installed: 1.0.2-2

3) Shared library dependencies for LUA 5.1-version:
$ ldd 5.1-bitop/bit.so
        linux-vdso.so.1 => (0x00007fffe4bfc000)
        libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f36f1bdc000)
        /lib64/ld-linux-x86-64.so.2 (0x00007f36f21b7000)

Notice how liblua5.1.so is missing from the list. On a Perl-script running Inline::LUA following error message will be emitted:
"error: error loading module 'bit' from file '/usr/lib/x86_64-linux-gnu/lua/5.1/bit.so':
        /usr/lib/x86_64-linux-gnu/lua/5.1/bit.so: undefined symbol: lua_gettop"

Info: Perl doesn't use LUA 5.2 in it's bindings, only LUA 5.1.

4) Build warnings gone, Perl-script working:
dpkg-shlibdeps: warning: symbol lua_gettop used by debian/lua-bitop/usr/lib/x86_64-linux-gnu/liblua5.1-bitop.so.0.0.0 found in none of the libraries

5) This is what I'd like to happen:
$ ldd /usr/lib/x86_64-linux-gnu/liblua5.1-bitop.so.0.0.0
        liblua5.1.so.0 => /usr/lib/x86_64-linux-gnu/liblua5.1.so.0 (0x00007fdc61c2d000)

I managed to manually build a library with linker options:
CLIB_CFLAGS=-Wl,--no-as-needed -llua5.1
and that fixes the issue.

This is affecting Ubuntu 16 also.

Here is a proof of failure:
#!/usr/bin/perl -w --

use strict;
use warnings;
use Inline;

# Sample LUA-code
my $lua = <<END_OF_CODE
require('bit')
require('math')

function lua_bitop_tester()
  test_vars = {}
  test_vars['bitmap'] = 1

  print(bit.band(test_vars['bitmap'], bit.lshift(1, 0)))
  print(tonumber((bit.band(test_vars['bitmap'], bit.lshift(1, 0))) or 0) > 0)
end
END_OF_CODE
;

# Introduce the lua_bitop_tester() function into Perl-world
Inline->bind( Lua => $lua );

# Call LUA-code
lua_bitop_tester();

# Should output
#1
#true
# ... if working correctly
# Will output:
# error: error loading module 'bit' from file '/usr/lib/x86_64-linux-gnu/lua/5.1/bit.so':
# ... when using Ubuntu package

That piece of Perl-code will fail with default package and run successfully when rebuilt with proper dynamic dependencies.
