I've seen these kind of errors always when linking a file into a shared
library that wasn't compiled with the -fPIC flag (with good candidates
always being libgcc.a and libstdc++.a). I would first make sure that all .o
files are compiled with this flag and then examine the line which links
together libperl.so (-Wl,--verbose might be a useful flag for gcc.)
well, the flags passed to various commands are the same for both the working
and failing cases. the compiler and/or binutils being different causes the

That seems to confuse me a bit. The error might well be in the gcc setup,
but binutils shouldn't affect the behaviour. At least we've got vanilla GNU
binutils 2.10.1 running here without any problems (NetBSD sparc 1.5).
it may be an interaction with "new" gcc and "new" binutils. i will note
that my new binutils were 2.11 based.
i do hope to soon track this down more fully.
