Error while compiling Bootstrap-styl npm module file during Meteor app build

The Stylus compiler built in the Meteor.js builder gives me the following error:

cannot perform $line-height-computed * 0.75
   at ".table-responsive"
   ({}/node_modules/bootstrap-styl/bootstrap/tables.styl:147:1)

during the build while attempting to compile the tables.styl file of the bootstrap-styl npm module that I added in my Meteor app.

Any idea what the problem might be? I am using:

meteor 1.4.2.3 on OS X El Capitan
bootstrap stylus 3.3.7 added to my app by doing

meteor npm install bootstrap-styl
and the following files from this module:

import button from '/node_modules/bootstrap-styl/js/button.js'

@import '{}/node_modules/bootstrap-styl/bootstrap/tables.styl'

@import '{}/node_modules/bootstrap-styl/bootstrap/mixins/table-row.styl'

@import '{}/node_modules/bootstrap-styl/bootstrap/buttons.styl'

@import '{}/node_modules/bootstrap-styl/bootstrap/mixins/table-row.styl'

Any idea what could be the problem?

It seems to have been an import order problem.

Now that I have:

@import '{}/node_modules/bootstrap-styl/bootstrap/variables'
@import '{}/node_modules/bootstrap-styl/bootstrap/mixins/table-row'
@import '{}/node_modules/bootstrap-styl/bootstrap/tables'
@import '{}/node_modules/bootstrap-styl/bootstrap/mixins/buttons'
@import '{}/node_modules/bootstrap-styl/bootstrap/buttons'

the compiling error is gone.
