Re: [NEW] btop++

Hi, 

With the 7.5 release, I tried again, and finally btop now builds with attached port. However, I'm struggling with the PLIST file, it seems the fake install is messing up the prefix somehow. 

Can someone help?

Cheers,

Jos

the attached tar does build with clang 16 but it still fails:
