I have build error when trying to build latest 1.5.1 on ubuntu `Linux vad-1025C 5.3.0-61-generic #55~18.04.1-Ubuntu SMP Mon Jun 22 16:40:46 UTC 2020 i686 i686 i686 GNU/Linux`

```julia

```

obviously error is in extra dot in `SuiteSparse.v5.4.0-6..tar.gz` - but how do I fix it?

thank you in advance

```julia

```

You need to install `gfortran`.

thank you, that helped! 👍🏻

though, seems like missing gfortran made configuration scripts out of control
