The linkage failure is because the linker didn't find the Tachyon
library (libtachyon.a) in the directory you listed:
/soft/vmd-1.9.1.src/lib/tachyon/compile/linux/libtachyon
You should specify the directory that contains the file libtachyon.a,
and the linker should complete without error.
Cheers,
John Stone
