Typo in installation document

[toddmo]

In https://mathics-development-guide.readthedocs.io/en/latest/installing.html,

there's a typo.

The line

$ apt-get install python-dev libsqlite3-devp python-setuptools liblapack-dev llvm-dev

should be

$ apt-get install python-dev libsqlite3-dev python-setuptools liblapack-dev llvm-dev

libsqlite3-devp has an extra p

The typo is actually in the mathics-development-guide repo. Fixed in https://github.com/Mathics3/mathics-development-guide/commit/b78cf64240dce56ffe303d3eb5fe14ceab46bcf7
