Created attachment 346458 [details, diff] lzo-2.06-mingw32-dll.patch I’ll suggest this trival change to upstream. It does make sense for upstreams, I think, to use -no-undefined in cases where the shared object cleanly and directly depends on other dynamic objects. The only case where -no-undefined probably shouldn’t be in target_LDFLAGS is in some odd scenario where the libraries providing certain symbols will only ever be loaded by dlopen()ing particular libraries before dlopen()ing the shared object or through LD_PRELOAD. I.e., -no-undefined applies to almost all situations and is the rule rather than the exception. It is too bad that libtool defaults to assuming that undefined symbols is normal. I don’t expect many Windows users of liblzo to be inclined to want the DLL version, but it is nice to be able to provide it if desired and this patch permits that.
Patch sent upstream, pending upstream coordination.
Upstream reports that they have already made this change in their development tree and it will show up in the next version, so I will put this patch in a new ebuild revision since upstream has no issue with it.

Thanks @binki, it seems it's not included in current portage tree.
looks like this patch is included in upstream lzo2-2.0.8 release, so adding bug 515238 to deps, from which 2.08 will be added to Portage
2.0.8 in portage
