Comment # 4 on bug 1205043 from alexander tismer

Thank you for your comments. 

All libboost*1_75_0 libraries are installed from the Main-Repository

```
Alias          : repo-oss
Name           : Main Repository
URI            : http://download.opensuse.org/distribution/leap/15.4/repo/oss/
```

The zypper output of the command 

```
zypper search -s libboost_filesystem
```

gives

```

You mentioned that `libpoppler-devel` requires EXACTLY `1_66_0`. Then, I think,
I misunderstand the output of zypper:
```
'libboost_headers-devel >= 1.58'
```

This does not mean that the MINIMUM required version is 1.58?

But in the end, and as you also mentioned, I know that downgrading will fix the
problem. I was confused about zypper's output. I thought the requirement of at
least libboost version 1.58 is also fulfilled by version 1.75.
