Hi, I'm installing Plone from source onto a RedHat EL4 test server using http://plone.org/documentation/how-to/setup-from-source as my reference. I have got as far as "Setting up the software" but this is the part I'm having difficulty understanding "Extract the Plone tarball. This will give you a folder called Plone-2.1 (presuming you have version 2.1), in which you will see a number of products folders, such as CMFPlone and CMFCore. Copy all these product folders (not the top-level Plone- folder) into ~/zope/instance1/Products/." The Plone-2.1.2/CMFPlone/install.txt lists these as mandatory **REQUIREMENTS** **MANDATORY** - Zope 2.7.8 (or 2.8.5) - CMF 1.5.5 (not 1.4) Included in the Plone tarball - CMFQuickInstallerTool 1.5.5 or newer - GroupUserFolder 3.5 or newer - BTreeFolder2 1.0.2 or newer - CMFFormController 1.0.6 or newer - SecureMailHost 1.0.1 or newer - Archetypes 1.3.6 or newer - ATContentTypes 1.0.2 or newer - ATReferenceBrowserWidget 1.1 or newer - ResourceRegistries 1.1 or newer - ExtendedPathIndex 2.2 or newer - CMFDynamicViewFTI 1.0.1 or newer - Python Imaging Library 1.1.5 or newer Not included in the Plone tarball http://effbot.org/downloads/#Imaging Note: You have to build PIL with jpeg and png support. See the README of PIL for more information. - Placeless Translation Service 1.2.5 or newer - PloneTranslations 2.1.2 - PloneLanguageTool 0.9 or newer as neither CMF 1.5.5 or Python Imaging Library 1.1.5 are included in the Plone-2.1.2 tar ball I am wondering; which is correct the "install.txt" or is it the "how-to/setup-from-source"?
