Hi,

There is a user of my software who has a problem, Gdk.cairo\_available?  
not found when loading gtk2:

[https://www.zarb.org/pipermail/booh-discuss/2008-June/000267.html](https://www.zarb.org/pipermail/booh-discuss/2008-June/000267.html)

He said he’s using 0.17.0-rc1, with pixman and cairo in non standard  
directory:

Does it say something? From reading the code, Gdk.cairo\_available?  
should always be ok I guess!?

Yes.  
It seems that old gtk2.so is loaded.

Confirmation:  
% strace ruby bin/booh 2\>&1 | grep gtk2.so

## Thanks,

I had similar problems after updated ruby and did a make && make install  
again.

A make clean & complete new build resolved the problem.
