>Description:
as requested, here is the bug report for the build time problems concerning gcc.

1. as indicated in my post to pkgsrc-users:
Just came across this head-scratching anomaly...

When compiling gcc (here 4.7.2), libiberty/sha1.c bombs out if 
pkgsrc/security/skey is installed as apparently this packages installs a sha1.h 
in ${PREFIX}/include which occludes /usr/include/sha1.h (and 
/usr/include/sys/sha1.h for needed integer types.

Is this a problem with skey, or libiberty which isn't detecting whether
or not (in configure, for example) the sha1.h in the path includes sys/types.h 
or not.

to complete the gcc build, simply deinstall skey and reinstall later if need be.

Might this (skey's sha1.h ) cause build problems elsewhere (similar to 
libiberty)? 


2. the second problem is if gcc-go is included in options, the build (at least 
with ABI=64) fails with:

>How-To-Repeat:
for 

problem 1: install skey and try to rebuild

problem 2: add gcc-go to PKG_OPTIONS.gcc47
>Fix:
for 
problem 1: deinstall skey before trying to build

problem 2: the following hacks.mk seems to work (at least until the illumos fix 
hits the streets):
