I use `zypper si` command to install source package in SUSE: 

```
localhost:/dev/disk/by-id # zypper si zlib
Reading installed packages...
Loading repository data...
Resolving package dependencies...

The following source package is going to be installed:
  zlib

1 source package to install.
Overall download size: 587.0 KiB. Already cached: 0 B. After the operation, additional 597.7 KiB will be used.
Continue? [y/n/? shows all options] (y): y
Checking for file conflicts: ........................................................................................................[done]

```

But when I use the command: `zypper se` to check package state, it shows "not installed": 

```
localhost:/dev/disk/by-id # zypper se zlib
Loading repository data...
Reading installed packages...

S | Name | Summary                  | Type
--+------+--------------------------+-----------
  | zlib | Data Compression Library | srcpackage

```

Could anyone give some clues?
