in reply to XS namespace problem

Its best if you provide a copy of what you have so far for us to try.

The build process starts with perl Makefile.PL and ends with make, and you should show everything that gets printed to the screen by those (or their equivalents -- Build.PL...).

When you encounter a problem, make sure you do make realclean before reporting any bugs (especially during development).

Judging by the .lds I'm guessing that you're not using ExtUtils::MakeMaker (you're using ExtUtils::CBuilder), so make sure you have the latest and the greatest version of it (same goes for ExtUtils::MakeMaker and ExtUtils::ParseXS).

Try "findstr /s /i boot_Tie__PureDB *" and see if Node.c shows up as containing that string (it should). If it doesn't, make sure you make realclean and try again.

I run a Win32 PPM repository for perl 5.6.x and 5.8.x -- I take requests (README).
