It should not be that hard.  You can just add your library to the
final link step in the src/Makefile and either remove blas from the
list of subdirectories to process in the libcruft/Makefile or delete
the specific files from the libcruft/blas directory that your library
replaces, whichever is appropriate.

Is the library free software?
