 Vidalia compiled different way, why not to compile it again - the same way
 as it was compiled for TBB 2.2.35-5?

 I think it '''is''' pretty obvious what's going on (ie machine used for
 compiling got upgraded from 10.5 to 10.6+). It's common problem, check out
 those articles for possible solutions:

 and

 In this case, it is obvious that the application was incorrectly built on
 OS X 10.6 (or newer) machine for a 10.5 machine. A developer can fix this
 by considering three things:

 1. Using the correct compiler parameters:
 {{{gcc-4.2 -mmacosx-version-min=10.5 -isysroot
 /Developer/SDKs/MacOSX10.5.sdk}}}...

 2. Using the correct linker settings (setting environment variable
 '''before''' link command). This is required, so that the OS X 10.6 linker
 will not use the loader command {{{'LC_DYLD_INFO_ONLY' (=0x80000022)}}},
 because OS X 10.5 does not understand it.

 {{{
 export MACOSX_DEPLOYMENT_TARGET=10.5
 (or setenv MACOSX_DEPLOYMENT_TARGET=10.5)
 }}}

 #. When this is done, one can check if the application was correctly built
 for OS X 10.5 by running 'otool':

 {{{otool -l binary}}}

 The correct binary should not contain any '{{{LC_DYLD_INFO_ONLY}}}' load
 commands (only '{{{LC_DYLD_INFO}}}' commands).
