You're missing a transfer vector (on VAX) or symbol vector (AXP).  See chapter 
4 of the Linker manual for the details.  If you are on VAX and have a V5.x 
document set, see also the "Guide to Creating Modular Procedures".

If you're on VAX and you want a quick-and-dirty method, use a linker options
file that has lines such as the following:

	UNIVERSAL=routine1,routine2,routine3,....

On AXP, it's easier - the following is an example:

   $ LINK/SHAREABLE   MY_MATH, SYS$INPUT/OPT
   GSMATCH=lequal,1,1000
   SYMBOL_VECTOR=(myadd=PROCEDURE,-
                          mysub=PROCEDURE,-
                          mymul=PROCEDURE,-
                          mydiv=PROCEDURE,-
                          my_symbol=DATA,-
                          my_data=PSECT)
