Re: [boost] Re: 1.31.0 release candidate 3

 From the Darwin dept.
I checked out a clean copy of boost using the tag Version_1_31_0 and ran 
the regression tests via tools/regression/run_tests.sh shell script.  My 
compiler is:
gcc (GCC) 3.3 20030304 (Apple Computer, Inc. build 1495)

And the following pertinent environment variables were set prior to my 
test runs:
TOOLS=darwin
PYTHON_ROOT=/System/Library/Frameworks/Python.framework/Versions/2.3
PYTHON_VERSION=2.3

I compared (via eyeball) the results against the darwin results 
available from the boost web page.  The existing results appear to be 
mostly the same, but I notice that the Boost.Python results are not run 
on that machine (see 
http://boost.sourceforge.net/regression-logs/cs-Darwin.html).  Many 
python tests seem to fail on my machine (A G4 laptop running Panther, 
minus the most recent Software Update).  Specifically, all 'run_pyd' 
tests fail.  The results are along the lines of the following:

etcetera, etcetera, etcetera.

To see if I could make some sense of this, I by hand made my way to the 
"hello world" example in libs/python/example/tutorial, and built it 
using bjam.  Then, upon
backtracking and finding the hello.so file (in 
bin/boost/libs/python/example/tutorial/hello.so/darwin/debug/shared-linkable-true), 
I tried to run python got the following feedback:

 >>> import hello
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
ImportError: Failure linking new module: 
../../../bin/boost/libs/python/build/libboost_python.dylib/darwin/debug/shared-linkable-true/libboost_python.dylib: 
dyld: python can't open library: 
../../../bin/boost/libs/python/build/libboost_python.dylib/darwin/debug/shared-linkable-true/libboost_python.dylib  
(No such file or directory, errno = 2)

This seems to make sense, since in this case, the above search path 
doesn't have enough "../" repetitions in it.  moving hello.so to a 
location where the above path is "relatively" valid (ie. three 
directories down from the "bin" directory) causes it to work correctly.

Since I'm not very familiar with Boost.Build or Boost Jam, or dynamic 
linking on darwin for that matter, I don't know if these errors are due 
to some oversight on my part.  I'd appreciate any input from others 
using a similar configuration.

Cheers,
