 Bigger Bigger  Smaller Smaller  Reset Reset

Hi, I have just installed arduino ide and added gsm-sheild-arduino ( http://code.google.com/p/gsm-shield-arduino/ ) library to it. But when I try to verify any of the examples from GSMSHIELD I get following errors. Am I doing sth wrong? I don't have problems with other examples.
Code:

 Bigger Bigger  Smaller Smaller  Reset Reset

I have found solution.
I am using arduino ide in 1.0.3 version (installed on my fedora by "yum install arduino"), but found that there is 1.5 version - but still beta.
In 1.5 there is one fix to F() function which I applied in my 1.0.3, which is one line in WString.h that needs to be changed:
Code:
#define F(string_literal) (reinterpret_cast<__FlashStringHelper *>(PSTR(string_literal)))
to
Code:
#define F(string_literal) (reinterpret_cast<const __FlashStringHelper *>(PSTR(string_literal)))

I am also having trouble compiling examples of gsm-sheild-arduino ( http://code.google.com/p/gsm-shield-arduino/ ) library. I Get list of errors.

I oppened up WStrings.h file and saw the following line already there:
#define F(string_literal) (reinterpret_cast<const __FlashStringHelper *>(PSTR(string_literal)))

Can someone suggest what might be wrong with gsm-shield-arduino library?

regards

I'm also having this problem!

Any help would be greatly appreciated.

Here is what my errors are saying when trying to compile the TestModem example:
