Package pageslts prints out this warning since I use pdfpages and hyperref in the same document.
Package pageslts Warning: Package pdfpages detected. (pageslts) Using hyperref with pdfpages can cause problems. See (pageslts) ftp://ftp.ctan.org/tex-archive/ (pageslts) macros/latex/contrib/pax/ (pageslts) for project pax (PDFAnnotExtractor)..
What does this mean? Am I supposed to change anything in the document or when am I going to see any problem?

pdfpageswill be lost, but this is known. The PAX program by H. Oberdiek can be used to reinstate them. – egreg Sep 23 '12 at 16:50
