OK, thank you for the link.
The package installed correctly (not counting the fact that I have 
downloaded the i386 package whereas the labels in the installation 
window were always PPC - this seems to be a label-only issue).

The compiler works fine, but somehow I cannot link:

~/temp/ada $ gnatmake hello
gcc -c hello.adb
gnatbind -x hello.ali
gnatlink hello.ali
/usr/bin/ld: Undefined symbols:
__Unwind_Resume
__Unwind_ForcedUnwind
__Unwind_GetDataRelBase
__Unwind_GetIP
__Unwind_GetLanguageSpecificData
__Unwind_GetRegionStart
__Unwind_GetTextRelBase
__Unwind_RaiseException
__Unwind_SetGR
__Unwind_SetIP
collect2: ld returned 1 exit status
gnatlink: cannot call /usr/local/ada-4.2/bin/gcc
gnatmake: *** link failed.
~/temp/ada $

I have noticed that there is a separate toolchain, complete together 
with gcc, in /usr/local/ada-4.2/bin, so I have added that to my PATH (at 
the beginning).
Still, the linker fails.

Running gnatlink -v -v on the .ali file gives this output:

~/temp/ada $ gnatlink -v -v hello.ali

Any thoughts?

comp.lang.ada is responsive, too! ;-)
