Dear all,

when installing tioga

[http://www.kitp.ucsb.edu/~paxton/tioga.html](http://www.kitp.ucsb.edu/~paxton/tioga.html),

I get a cannot read symbol, bad value error (see below).  
I tried the gem and QUICK\_INSTALL and HOME\_INSTALL  
variants.  
Has somebody else had this problem ? How did they solve it -  
change compilation flags for -fPIC ?

Best regards,

Axel

wouldn’t it make more sense to write on the tioga user’s mailing list  
or file a bug on their rubyforge project?

Dear Ryan,  
nice to know that there is a special user’s mailing list. I missed that.

Best regards,
