interop.ADOX and interop.ADODB assemblies

Question

when creating a strongly named library assembly that contains references to interop.ADOX and interop.ADODB name spaces and this library assembly is being referenced or accessed by an .APSX page via the @ASSEMBLY/@IMPORT page keywords, the library assembly fails with a file not found exception.Here's the message text:

System.IO.FileNotFoundException was unhandled by user code
  Message="Could not load file or assembly 'Interop.ADOX, Version=2.8.0.0, Culture=neutral, PublicKeyToken=0e98756fa7be071a' or one of its dependencies. The system cannot find the file specified."

?Question: how are these assemblies put in the GAC. I tried the GACUTIL with no errors and the /lr reports the assembly as being in the GAC and yet I keep getting the error, then I reset iis, nothing, then I re-booted and nothing.

the library assembly is a SharePoint library trying to get the contents of a survey into an access database...

Thanks for any and all Help
