Sorry, I did not explain the situation clear enough. I was at 2.7, and wanted to install a 2.7 upgrade because of a bug. If memory serves me, from 2.7.3 to 2.7.6 But that started mounting about missing db stuff, and having to install a py= /db of choice. That is where I ran into the catch22, installing a db required py-tools, whi= ch in turn starts to try to upgrade python from 2.7.3 to 2.7.6. Then I cleaned/removed al python stuff, and tried again. First with 2.7 and when that did not work, I tried 3.3 with the same result.= I tried with portinstall/portupgrade as well as make && make install, but bo= th fail for the same reason. So atm I have no python at al. > So far there are still many modules that don't work with 3.x so you may > want to use 2.7 if you want python with more than the default modules. >=20 > The default python is still 2.7, if you want to use 3.3 then you might > want to add > DEFAULT_VERSIONS=3DPYTHON=3D3.3 PYTHON3=3D3.3 > to your /etc/make.conf >=20 >> The system everytime refuses to install because of missing a database: >>=20 >> pkg-static: >> lstat(/home2/usr/ports/lang/python33/work/stage/usr/local/lib/python3.3/l= ib-dynload/_dbm.so): >> No such file or directory >> *** [fake-pkg] Error code 74 >>=20 >> [ replace python33 by python27 te get the similar error for 2.7 ] >=20 > This would indicate that the dbm module wasn't built.

Using command line in putty. I will try again, and scan de build output for more errors. So there should b= e an error building the part in the stage tree? >=20 > gettext libiconv and gmake are the only things that need to be installed > before python to build.

That would be the alternative, but I only do that, if nothing else works. I've grown to always build my stuff. >=20 > What FreeBSD version are you using? I386 9.2-STABLE --WjW=
