Thanks to Casper Dik:
You need to install SUNWarc from CD (weird, w/o it you shouldn't be 
able to link anything)
/usr/lib/libmail.a is in package SUNWarc
system      SUNWarc        Archive Libraries
Q2. ">In a situation like this where a library can't be found. How 
does one

Thanks to Glenn Satchell:
Most standard Solaris libraries will be found in /usr/lib. If you link 
something caled -lmail, then th ecorresponding file name will be one 
of libmail.so.X.Y or libmail.a The firt is a shared or dynamic library 
and X and Y will be version numbers.
X windows and Openwindows libraries are in /usr/openwin/lib or 
/usr/dt/lib.
Anything else is either not part of Solaris or is a part of the 
package.
And James Noad:
Try installing the GNU findutils: (294k)
ftp://sunsite.doc.ic.ac.uk/packages/gnu/findutils-4.1.tar.gz
This packages basically builds a database by doing a "find" on your 
filesystem which you can very quickly search.
