Unable to open the control file in set_flags_from_control

[GoogleCodeExporter]

Hi, 
using svn snapshot r198 on OpenWrt for etrax platform I get this error:

$ opkg install strace
Installing strace (4.5.16-2) to root...
Downloading
http://download.tuxfamily.org/crisos/repository/darwinfox/all//strace_4.5.16-2_c
ris.ipk
can't get //usr/lib/opkg/info/strace.control open for read
Configuring strace
Collected errors:
 * Unable to open the control file in  set_flags_from_control

Please note that this happens for any package inside
http://download.tuxfamily.org/crisos/repository/darwinfox/all

The problem appear to affect only this architecture but please don't
discard it as workforme I can provide a lot of information about this bug.

I attach also the full log using strace; on this log at line opkg.log:2513
you can see that opkg try to open control file in RDONLY instead of WRONLY
like happens for list file at line 2518

Regards

Hi ticktock35

I just recompile opkg with the patch previously posted and the little debug 
info:
Index: libopkg/opkg_install.c
===================================================================

      if (old_pkg)
      remove_obsolete_maintainer_scripts(conf, pkg, old_pkg);
      sprintf_alloc(&prefix, "%s.", pkg->name);
+   printf("%s\n",prefix);
      ret = pkg_extract_control_files_to_dir_with_prefix(pkg,
                            pkg->dest->info_dir,
                            prefix);

The result was:

# opkg install strace

strace.

As you can see the value of prefix is "strace." after sprintf_alloc.
