There are some known bugs.

Plugin attachment is not in its final form.  It will change
before the stable release.  There is some question of 
how it should work.  Your comments will be helpful.

No.  Plugins are usually built after gnucap is compiled and 
installed.  Plugins require access to the gnucap header files.  
Eventually, the header files will be installed somewhere 
when gnucap is installed.  Eventually, you will be able at 
"attach" the source files without manually compiling first.

Plugins are distributed separately, so they can be added later.  
If you are on a shared system, this allows gnucap to be installed 
for everyone to use, and plugins to be in your own space.

Plugins do not yet have a "make install".  Actually, all of the 
"make install" has not been updated for plugins.

With no / it searches in the lib path.  If you want it there, 
you need to manually put it there.

I don't know what that means.  I never saw that message.
Here's a guess:  Maybe the plugin is compiled for a different
architecture than the main program.  Maybe the compiler
switches are different.  Let me know if you can figure it out.

Try ".get" .. or change it as suggesed in my other mail.

That may be the problem.  I have not tested it there.
