how to link compiler logical from mmk

Hi,

I am trying to build a perl5.10.0 using MMK.
I am linking against the 8.3 decc$shr on a 7.3-2 system.
Compiler virsion of the & 7.3-2 is below.
$ cc/ver
DEC C V5.7-006 on OpenVMS Alpha V7.3-2
$

For compiling the perl5.10.0 i need minimum DECC v6.0.
By defining the logical with new compiler i am  getting  crash because the
mmk is not inheriting either symbols or logical names from the parent
process. At command prompt the file is getting compiled with the logical
defined.. So I need to include the process of calling .com file which
defines the compiler logical in mmk.

*how can I add my own command file to be called from mmk?

*Thanks in advance.
