Error installing/using with Dillo 3.2.0 on macOS 26

[acidus99]

I am running into some trouble installing/using this plugin.

I installed Dillo via homebrew using the instructions for macOS here.

When I downloaded this plugin to my ~/Downloads/ folder, and ran make install I got an error:

my-computer:dillo-plugin-gemini-main someuser$ make install
mkdir -p ~/.dillo/dpi/gemini
if [ -f /etc/dillo/dpidrc ]; then cp /etc/dillo/dpidrc /Users/someuser/.dillo/dpidrc; \
	elif [ -f /usr/local/etc/dillo/dpidrc ]; then cp /usr/local/etc/dillo/dpidrc /Users/someuser/.dillo/dpidrc; \
	else echo "Can't find dpidrc, is dillo installed?"; false; fi
Can't find dpidrc, is dillo installed?
make: *** [/Users/someuser/.dillo/dpidrc] Error 1

The "Can't find dpidrc, is dillo installed?" error is odd. It seems to be looking for the dpidrc file in ~/.dillo/. When I checked that directory, I saw it was empty (despite having run and used dillo several times).

Running which dillo gave me /opt/homebrew/bin/dillo, which was a symlink to /opt/homebrew/Cellar/dillo/3.2.0/bin/dillo. Looking in /opt/homebrew/Cellar/dillo/3.2.0/ I saw a etc/dillo/directory, and sure enough inside was a dpidrc file:

my-computer:dillo someuser$ pwd
/opt/homebrew/Cellar/dillo/3.2.0/etc/dillo
my-computer:dillo someuser$ ls
dillorc       domainrc      dpi/          dpidrc        hsts_preload  keysrc

I modified the Makefile for this plugin to use DILLO_DIR = /opt/homebrew/Cellar/dillo/3.2.0/etc/dillo/ and ran make install again:

my-computer:dillo-plugin-gemini-main someuser$ make
Use 'make install' to install
Use 'make uninstall' to uninstall
my-computer:dillo-plugin-gemini-main someuser$ make install
grep -q '^proto.gemini=gemini' /opt/homebrew/Cellar/dillo/3.2.0/etc/dillo//dpidrc || echo 'proto.gemini=gemini/gemini.filter.dpi' >> /opt/homebrew/Cellar/dillo/3.2.0/etc/dillo//dpidrc
dpidc stop || true

mkdir -p /opt/homebrew/Cellar/dillo/3.2.0/etc/dillo//dpi/gemini
cp -f gemini.filter.dpi /opt/homebrew/Cellar/dillo/3.2.0/etc/dillo//dpi/gemini
cp -f style.css /opt/homebrew/Cellar/dillo/3.2.0/etc/dillo//dpi/gemini

However when attempting to navigate to a gemini:// I get an error:

This is probably a mistake I made by modifying the Makefile. However I noticed that the dpidrc file does now have a protocol handler for Gemini installed:

my-computer:dillo someuser$ cat dpidrc 
dpi_dir=/opt/homebrew/Cellar/dillo/3.2.0/lib/dillo/dpi

proto.file=file/file.dpi
proto.ftp=ftp/ftp.filter.dpi
proto.data=datauri/datauri.filter.dpi
proto.gemini=gemini/gemini.filter.dpi
my-computer:dillo someuser$ ls dpi
dpi/    dpidrc  
my-computer:dillo someuser$ ls dpi/gemini/
gemini.filter.dpi* style.css

What am I doing wrong to properly install the gemini plugin for Dillo 3.2 on macOS?
