[OS X TeX] dvisvgm and ghostscript

[Doris Behrendt via MacOSX-TeX]

Hi all,

I repeated the process (hoping that everything just is overwritten and not having to uninstall the ghostscript stuff).

This is the command I entered and the error I got:

dvisvgm --libgs=/usr/local/share/ghostscript/9.53.3/lib/libgs.dylib.9.53 --pdf ct-logo.pdf
ERROR: Ghostscript is required to process PDF files


This is the output of my terminal in the dir named lib:

(base) Doriss-Mac-mini:lib bd$ ls -l l*
-rw-r--r--  1 root  wheel      1468 Oct  7 01:37 landscap.ps
-rwxr-xr-x  1 root  wheel  18259520 Oct  7 02:28 libgs.dylib.9.53
-rw-r--r--  1 root  wheel      3736 Oct  7 01:37 lines.ps
(base) Doriss-Mac-mini:lib bd$ pwd
/usr/local/share/ghostscript/9.53.3/lib
(base) Doriss-Mac-mini:lib bd$ 


The output of list at least shows that there is no symbolic link, but the file is there.


And I found ONE strange thing:
The name of the package I downloaded ends with >>…53.3<<, but the header line of the Installer window ends with >>...53.2-Full<<.

The typo .2 instead of .3 could occur also in other places, right?
Can this be connected to the reason for my problems?
