[gdal-dev] GDAL/OGR missing READ capabilities

Hi All, and Happy Thanksgiving!

This is probably a silly question but here is the situation I am in with 
OGR.

 1. I had to reinstall a QEMU virtual machine with *CodeServer*
    installed. The OS is Alma Linux 9.5.
 2. My main coding environment is *R* and I am performing a lot of
    geospatial operations on a *Postgis* database.
 3. So, I installed GDAL because it is needed by the *sf* plugin of R --
    a toolbox for geospatial operations in R.
 4. I also need OGR to *import GPX files into the Postgis database*. I
    execute something like:
    `ogr2ogr -skipfailures -append -update -f 'PostgreSQL' -t_srs
    'EPSG:4326' 'PG: host=<internal_host> port=5432 dbname=<dbname>
    user=<username> password=<pwd>' -nln `
 5. BUT since I reinstalled GDAL, when executing the GPX importg
    procedure, I get this error:

```log

ERROR 6: OGR/GPX driver has not been built with read support. Expat 
library required
FAILURE:
Unable to open datasource `/mnt/gps/20241127-C.gpx' with the following 
drivers.

```

I have reinstalled the `expat` library but it did not help.

What have I done wrong?

Thank you for your help,

Stephen
