In trying to compile the new lyx2.0.1 I encounter the following errors:

however, dpkg-dev is installed
Is zlib.h present?
yes, as zlib1g, and it says:
compression library - runtime
zlib is a library implementing the deflate compression method found
in gzip and PKZIP. This package includes the shared library.
That package does not include the file zlib.h:
http://packages.debian.org/squeeze/amd64/zlib1g/filelist
You need zlib-dev:
http://packages.debian.org/squeeze/zlib1g-dev
http://packages.debian.org/squeeze/amd64/zlib1g-dev/filelist
which "includes the development support files".
Base packages, like zlib1g, include only the files need to *use* the
library. So to run LyX, you only need zlib1g, which LyX uses to zip
and unzip things. The *-dev packages, on the other hand, include
what you need to "link against" the library, that is, what you need
to *compile* programs that use that library. So, to compile LyX, you
need zlib1g-dev.
The same goes for the X packages and Qt packages. E.g., as well as
libqt4, you need libqt4-dev.

Thanks Richard for your careful explanation. Will try and report.
