I still obtain error when compile /usr/ports/math/scilab

[cblasius]

Hello!

Thank you for previous help  :-) !

I upgrade my port tree (cvsup) and all instaled ports (portupgrade
-a) and still  is problem with compiling /usr/ports/math/scilab. 
Especially with  port: /usr/ports/textproc/sablotron. Could someone help 
me with this issue. I want to use scilab for my work at university.

Thanks in advance.
Here is the output when I compiled sablotron.
