Strange makefile errors in multiple ports

[Oliver Iberien]

I seem to have messed something up somewhere, and peculiar instructions seem 
to have found their way in. An example is below:

--->  Checking for the latest package of 'devel/gettext'
--->  Fetching the package(s) for 'gettext-0.16.1' (devel/gettext)
--->  Fetching gettext-0.16.1
/var/tmp/portupgradeJwjg3x7H/gettext-0.16.1.tb100% of 2093 kB  248 kBps
--->  Downloaded as gettext-0.16.1.tbz
--->  Identifying the package /var/tmp/portupgradeJwjg3x7H/gettext-0.16.1.tbz
--->  Saved as /usr/ports/packages/All/gettext-0.16.1.tbz
--->  Skipping libiconv-1.9.2_2 (already installed)
--->  Found a package 
of 'devel/gettext': /usr/ports/packages/All/gettext-0.16.1.tbz 
(gettext-0.16.1)
--->  Located a package version 0.16.1 
(/usr/ports/packages/All/gettext-0.16.1.tbz)
--->  Upgrading 'gettext-0.14.5_2' to 'gettext-0.16.1' (devel/gettext) using a 
package
cd: can't cd to /usr/ports/multimedia/any2dvd
"Makefile", line 54: Could not 
find /usr/ports/print/cups-lpr/../../print/cups/Makefile.common
make: fatal errors encountered -- cannot continue
^C--->  Backing up the old version
--->  Uninstalling the old version

The section

cd: can't cd to /usr/ports/multimedia/any2dvd
"Makefile", line 54: Could not 
find /usr/ports/print/cups-lpr/../../print/cups/Makefile.common

appears often when installing both from packages and ports. I just stop it and 
the install continues. What could be going on here?

Thanks,

Oliver
