Hi

I have run Rails on Linux til now but now I have to use Vista. I use  
InstantRails 1.7 but when I try to install the ruby-debug gem it says  
that it misses an nmake program. Does anyone know what this is and how  
to solve it?

Many thanks in advance

Erik L.

gem install ruby-debug -v 0.9.3

0.10.0 doesn’t build correctly on windows, 0.9.3 comes with a  
precompiled binary.
