i tried the above stment and got htis:
lrwxrwxrwx 1 root root     19 2009-08-06 22:37 /usr/lib/libstdc++.so.6 ->
libstdc++.so.6.0.10
-rw-r--r-- 1 root root 950424 2009-03-17 05:58 /usr/lib/libstdc++.so.6.0.10

After that i tried some examples in Gem (the libstdcpp lib  loaded
sucessfully.) and it crashed with a new  error:

 segfault at b65c8a52 ip b65c8a52 sp bfc7dbe0 error 4 in
libgomp.so.1.0.0[b6a19000+7000]
 segfault at b7bc3014 ip b7f27b64 sp bf995624 error 7 in libpthread-2.9.so
[b7f21000+15000]

i tried to recompile gridflow ...and noticed the following error:

[objcpp] GNU/Apple ObjectiveC++ Compiler:
------------------------------------> missing (where is objc/Object.h ?) (*I
have dwnlded and installed gnu objective c++ compiler: gobjc++ but it still
gives this*)
[gem09] PureData GEM (source code) with m_holdname:
--------------------------> missing (gcc: error: ‘CPPExtern’ has not been
declared)
[gem08] PureData GEM (source code) without m_holdname:
-----------------------> missing (gcc compilation error)

could this be an issue?
