help with Dec C compiler install

[bad bob <sfmc68@bellatlantic.net>]

I am attempting to install dec c compiler for alpha linux on a debian
system (PC164-500).  I am new to linux so, pardon my stupidity if you
will.

I need some help understanding this set of outputs:
I used rpm to install the packages:
bard:/usr/local/ts10# rpm --install libots-2.2.7-2.alpha.rpm
error: failed dependencies:
        ld-linux.so.2 is needed by libots-2.2.7-2
        libc.so.6.1 is needed by libots-2.2.7-2
bard:/usr/local/ts10#     
>>>I don't understand these outputs, they don't seem to make sense.

bard:/usr/local/ts10# rpm --install cpml_ev5-5.1.0-2.alpha.rpm
error: failed dependencies:
        /bin/sh   is needed by cpml_ev5-5.1.0-2
bard:/usr/local/ts10#         
>>>This one really does not make sense, there is a /bin/sh function,
I had the symlink, deleted that, copied over bash with a new name,
sh, cause I have plenty of space on this beast.

bard:/usr/local/ts10# rpm --install ccc-6.2.9.506-1.alpha.rpm
error: failed dependencies:
        man is needed by ccc-6.2.9.506-1
        /bin/sh   is needed by ccc-6.2.9.506-1
        /bin/sh is needed by ccc-6.2.9.506-1
bard:/usr/local/ts10#          


>>thne I had the "brilliant" idea of isntalling this way:
bard:/usr/local/ts10# rpm --install --nodeps cpml_ev5-5.1.0-2.alpha.rpm
package cpml_ev5-5.1.0-2 is already installed
bard:/usr/local/ts10# rpm --install --nodeps ccc-6.2.9.506-1.alpha.rpm
package ccc-6.2.9.506-1 is already installed
bard:/usr/local/ts10# rpm --install --nodeps libots-2.2.7-2.alpha.rpm
package libots-2.2.7-2 is already installed
bard:/usr/local/ts10#            

Yes, I have picked up a good book on linux, am going thru all the docs,
but still ....
anyhelp greatly appreciated.
