Find attached the log.

Thanks,
Luca

Works fine for me. Did you maybe run restore_ports.tcl with a restrictive umask before it started setting its own?

I don't think so...I don't know waht restore_ports.tcl is...I'm using porticus.

Are you able to run this in MacPorts python2.7?

import xml.sax
parser = xml.sax.make_parser()

[lucaghera8@…]

Hi, thanks for your help.

I tried to run what you said in my shell. This is the result:

macbook-di-luca:Desktop luca$ python
Python 2.7.2 (default, Jul 21 2011, 10:46:54) 
[GCC 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2335.15.00)] on darwin

>>> import xml.sax
>>> parser = xml.sax.make_parser()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/xml/sax/__init__.py", line 93, in make_parser
    raise SAXReaderNotAvailable("No parsers found", None)
xml.sax._exceptions.SAXReaderNotAvailable: No parsers found

To be noticed that I didn't create a file with the commands. I directly entered them from the shell. I'm not sure this is what you mean in your previous message. Sorry but I'm not used to python, I've to setup it for a dependency.

Thanks, Luca

OK, so it's actually python's built-in XML module that is not working.

I still cannot compile and install py27-libxml2. Any news?

[marc.schlaich@…]

I am quite sure you are doing something terrible wrong on Lion. Porticus is not supported anymore. Try using the CLI.

Porticus is not compatible with either Lion (Mac OS X 10.7) or MacPorts 2.0

Hi Marc,

why are you saying that I'm working with Porticus? It was, but actually I also tried to install py26-libxml2 from the command line with the same result. Luca

Duplicate #30845 occurred with python26.

Yes, is the same problem...and it's going to be really annoying because a lot of ports depend (indirectly) to py26-libxml2.

Hi,

I have started with a new installation of macport but I have the same problem with both py{27,26}-libxml2.

However now I'm able to execute the commands you suggested without errors:

here is the execution:

I really don't know why but now I can compile both.

The only thing I did is deactivating py26-setuptools and installing py26-distribute. And I copied the _socket.so file to the lib-dynload directories of python26 and 27 because they were missing.

Can these actions be the solution??

Thanks, Luca

Really? You can now use xml.sax manually but you still get an error saying "<class 'xml.sax._exceptions.SAXReaderNotAvailable'> No parsers found" when you install py*-libxml2? Attach the full log from a new installation attempt.
