It looks like I am building with the gnu  compiler, but not linking with 
the gnu linker.  I assume I need to install gnu binutils?

I would appreciate if somebody could point me to the proper linker to use 
and where I can download it .

Thanks
Wolfgang

I can sort of almost tell you?  I don't know anything about HP/UX. 

gcc passes options that follow '-Wl' to the linker, but I suspect you're
not using the GNU linker because I don't recognize "-Wl,+h ... -Wl,+b" as
GNU linker options.  I would guess, though, that
"-Wl,/home/i3build/freetds/" is passing the unwanted path information to
the linker, which installs it in the ELF header (assuming HP/UX uses ELF
binaries). 

If you have GNU binutils installed and use ELF binaries, you can use
'readelf -d' to look at the rpath information.  I think this is what you
mean by "static path". 

HTH.
