[ncl-install] NCL 5.1.0 and libcurl

Wed Apr 8 18:18:04 MDT 2009

Hi Mary, thank you so much for the help!!!

With the followin symbolic link:

/usr/lib/libcurl.so.3 -> /usr/lib/libcurl.so

and this new example, NCL works perfectly.

By the way, I'm using a 32-bit linux system.

Best regards,

Mateus
