[strongSwan] undefined symbol: XXX in all dynamically-linked executables

[Shea Levy]

Hi all,

I just added strongswan to my distro's package manager [1], and it all
seems to build fine but if I try to run any of the dynamically linked
executables I get a symbol lookup error, e.g.:

> /nix/store/6idv2wv00yww34hny20ikmy0qn5bdb11-strongswan-5.2.0/bin/pki: symbol lookup error: /nix/store/6idv2wv00yww34hny20ikmy0qn5bdb11-strongswan-5.2.0/lib/ipsec/libstrongswan.so.0: undefined symbol: XXX

Note that that XXX is literally in the output. Any ideas for how to
debug this? There were no special configure flags other than --prefix
and the only dependency available to the build was gmp.

Thanks,
Shea
