NetBSD 5.1 pkgsrc webkit-gtk compiling problem on PowerMAC G4

After successful installation I've got working NetBSD 5.1/macppc and I tried to add some pkgs to use the MAC for workstation. Here what I've got:

NetBSD 5.1 (G4) #5: Sat Nov 19 19:39:08 EET 2011

Trying to compile some meta-pkgs like gnome or kde I ran into some problems.

webkit-gtk - Compilation fails on some file FastMalloc.cpp but all errors are redirected to /dev/null so I couldn't find how to fix this. There is also bug report from 2009 about this problem you can see it here http://mail-index.netbsd.org/pkgsrc-bugs/2009/02/01/msg030663.html. Here is the error I've got:

Still no solution which means that kde web browser and epiphany web browser will not be build. After 1-2 days searching on the net for solution I decided to solve the problem myself. After some tweaking of the GNUmakefile I finally got the error message that fails the compile process

Quick search over google and I found that there was such problem with compilation of webkit-gtk on other OS's on PowerPC arch. It seems that this is gcc compiler bug on macppc arch. Simple solution is to compile with -O0 (do not optimize) instead of -O2 option.

Just for now here is quick and dirty solution to this:
start building process and when GNUmakefile is generated stop the process with ctrl+c.
Now open generated GNUmakefile (usually in webkit-gtk/work/webkit-gtk-1.4.x/GNUmakefile) with some editor and replace all -O2 with -O0 then save and exit and continue the compilation process by entering the dir and typing: gmake


Here are some links for the solutions Í found:
debian solution - http://blog.gmane.org/gmane.linux.debian.ports.powerpc/month=20070801/page=8
webkit-gtk bug report - https://bugs.webkit.org/show_bug.cgi?id=14521
bug report to gcc - http://gcc.gnu.org/bugzilla/show_bug.cgi?id=10396

Unfortunately these solutions dont work on NetBSD and I'm not good enough with assembler to make myself a patch.

When this was fixed I ran into another error.

This can be fixed easy by upgrading your gettext package. cd pkgsrc/devel/gettext; make install
