extract pages from pdf file?

[Paul Goyette <paul%whooppee.com@localhost>]

I've got poppler-utils installed but the pdfunite tools complains
that the source files are encrypted.  I don't know how to decrypt
these pages as they were (successfully) extracted from a larger
document using pdfsplit.  xpdf has no problems rendering either
the source file nor the individual pages.

So, is there another pdf utility that I can use to recombine a few
pages from the original document?

TIA
