Description Hans 2011-11-19 14:46:10 UTC 
media-libs/tiff-4.0.0_beta7 links libtiff to liblzma, if the latter is installed during the configure phase:


readelf -d /usr/lib/libtiff.so.5

Dynamic section at offset 0x756d0 contains 27 entries:
  Tag        Type                         Name/Value
 0x0000000000000001 (NEEDED)             Shared library: [liblzma.so.5]
 0x0000000000000001 (NEEDED)             Shared library: [libjpeg.so.8]
 0x0000000000000001 (NEEDED)             Shared library: [libz.so.1]
 0x0000000000000001 (NEEDED)             Shared library: [libm.so.6]
 0x0000000000000001 (NEEDED)             Shared library: [libc.so.6]
 0x000000000000000e (SONAME)             Library soname: [libtiff.so.5]
[...]

This can be controlled via the configure script:
[...]
--disable-lzma          disable liblzma usage (required for LZMA2
                          compression, enabled by default)
[...]

So I suggest adding 
a) a USE flag for this (lzma would appropriate, I think)
b) $(use_enable lzma) in the src_configure step in the ebuild.

Thanks for your attention!

this is fixed in ebuild for 4.0.0 final
