It is indeed fixed in 1.7 - we will look at backporting a fix to 1.6

So I'm told - I've never tried it myself.

I presume the 1.4 series

You need to be on a node where LSF libraries have been installed so we can link against them

No - you either have to install to an NFS mount, or copy them yourself

It will be in whatever prefix you give to configure, under the "bin" subdirectory. There will be a wrapper compiler that you can use to build your program
