<para>
<productname>CVS</productname> has deficiencies. For example,
generating diffs that add or remove files requires write access to the
- CVS repository. To work around such difficiencies, use
+ CVS repository. To work around that deficiency, use
<productname>cvsutils</productname>, which is packaged in several
operating systems, and is available in source form at <ulink
url="http://www.red-bean.com/cvsutils/"></ulink>.

+ Note that building <productname>PostgreSQL</productname> from a CVS
+ pull requires reasonably up-to-date versions of <application>bison</>
+ and <application>flex</>, which are not needed to build from a distribution
+ tarball because the files made with them are pre-built in a tarball.
+ Otherwise the tool requirements are the same as building from source.
