Looks like you are lucky here :-)
What I get on an OpenSuse 64bit system is this:
./runtests.sh base
--- Running tests in base ---
base/coding/decoding.m:
FAIL: decoding version 2 of class NSValue
base/Functions/NSGeometry1.m:
FAIL: near identical points are equal
FAIL: near identical sizes are equal
FAIL: near identical rects are equal
base/KVC/mutable.m:
ofObject:<Lists: 0x685a90>
context:(null)
ofObject:<Lists: 0x685a90>

base/NSException/basic.m:
FAIL: working callStackSymbols ... if this has failed it is probably due
to a lack of support for objective-c method names (local symbols) in the
backtrace_symbols() function of your libc. If so, you might lobby your
operating system provider for a fix.
base/NSStream/socket.m:
FAIL: read www.google.com https
259 COMPLETED
7 context
6 FAIL
7 ofObject
5226 PASS
I know that the first four errors are probably down to numeric issues
and that the "ofObject" and "context" messages are caused by some NSLog
statements that get picked up wrongly by the result grepping mechanism.
In the end it is just the missing gtsl and the one problem you have as
well. But to somebody not in the know this looks different.
As for the IGNORE case, I would prefer the EXPECTED_FAIL that Nicola
suggested.
