cannot install in Delphi5

[ErikL]

Has anyone ever tried to install the latest zeosdbo in Delphi5?
I tried.
Had to make several change to the code:
unit dateutils, types, variants all not exist in D5.

But after a few hours I got everything compiled.

Then tried to install the ZComponents.bpl and got error message:

"The procedure entry point @Db@TdateSet@Interna;Post$qqrv could not be located in the dynamic link library Vcldb50.bpl."

Who can help please?
