Can't locate IO/Compress/Lzm

使用theos的时候，打包出错如下：

Can't locate IO/Compress/Lzma.pm in @INC (you may need to install the IO::Compress::Lzma module) ...

解决办法：

1、/opt/theos/vendor/dm.pl/dm.pl
注释掉第12、13行
#use IO::Compress::Lzma;
#use IO::Compress::Xz;

2、/opt/theos/makefiles/package/deb.mk
第6行lzma改为gzip
_THEOS_PLATFORM_DPKG_DEB_COMPRESSION ?= gzip

重新make package，成功了。
