freebsd : 10 : sasl lib : which package?

[Mayuresh Kathe]

hello,

i am trying to compile mutt-1.5.22 with sasl support.
this is because the mutt available through pkg doesn't
support it.

while doing the pre-make configure, the following error
messages were thrown up;
checking for library containing sasl_encode64... no
configure: error: could not find sasl lib

may i know which package to install to get the above
library?

thanks,

~mayuresh
